In "dir_struct", each exclusion element in the exclusion stack records a
base string (pointer to the beginning with length) so that we can tell
where it came from, but this pointer is just pointing at the parameter
that is given by the caller to the push_exclude_per_directory()
function.

While read_directory_recursive() runs, calls to excluded() makes use
the data in the exclusion elements, including this base string.  The
caller of read_directory_recursive() is not supposed to free the
buffer it gave to push_exclude_per_directory() earlier, until it
returns.

The test case Bruce Stephens gave in the mailing list discussion
was simplified and added to the t3700 test.

Customize diff-options depending on particular command as follows,
mostly to make git-diff and git-format-patch manuals less confusing:

* git-format-patch:

  - Mark --patch-with-stat as being the default.

  - Change -p description so that it matches what it actually does and
    so that it doesn't refer to absent "section on generating
    patches".

* git-diff: mark -p as being the default.

* git-diff-index/git-diff-files/git-diff-tree: mark --raw as being
  the default.

There are inconsistencies in the way commands currently handle
the core.excludesfile configuration variable.  The problem is
the variable is too new to be noticed by anything other than
git-add and git-status.

 * git-ls-files does not notice any of the "ignore" files by
   default, as it predates the standardized set of ignore files.
   The calling scripts established the convention to use
   .git/info/exclude, .gitignore, and later core.excludesfile.

 * git-add and git-status know about it because they call
   add_excludes_from_file() directly with their own notion of
   which standard set of ignore files to use.  This is just a
   stupid duplication of code that need to be updated every time
   the definition of the standard set of ignore files is
   changed.

 * git-read-tree takes --exclude-per-directory=<gitignore>,
   not because the flexibility was needed.  Again, this was
   because the option predates the standardization of the ignore
   files.

 * git-merge-recursive uses hardcoded per-directory .gitignore
   and nothing else.  git-clean (scripted version) does not
   honor core.* because its call to underlying ls-files does not
   know about it.  git-clean in C (parked in 'pu') doesn't either.

We probably could change git-ls-files to use the standard set
when no excludes are specified on the command line and ignore
processing was asked, or something like that, but that will be a
change in semantics and might break people's scripts in a subtle
way.  I am somewhat reluctant to make such a change.

On the other hand, I think it makes perfect sense to fix
git-read-tree, git-merge-recursive and git-clean to follow the
same rule as other commands.  I do not think of a valid use case
to give an exclude-per-directory that is nonstandard to
read-tree command, outside a "negative" test in the t1004 test
script.

This patch is the first step to untangle this mess.

The next step would be to teach read-tree, merge-recursive and
clean (in C) to use setup_standard_excludes().

From version 1.72 it will replace all dots in roff requests with U+2302
("house" character), and add escaping in output for all instances of dot
that are not in roff requests. This caused the ".ft" hack forcing
monospace font in listingblocks to end up as "\&.ft" and being visible
in the resulting man page.

The fix adds a DOCBOOK_XSL_172 build variable that will disable the
hack. To allow this variable to be defined in config.mak it also moves
build variable handling below the inclusion of config.mak.

Solaris 9's vsnprintf implementation returns -1 if we pass it a
buffer of length 0.  The only way to get it to give us the actual
length necessary for the formatted string is to grow the buffer
out to have at least 1 byte available in the strbuf and then ask
it to compute the length.

If the available space is 0 I'm growing it out by 64 to ensure
we will get an accurate length estimate from all implementations.
Some callers may need to grow the strbuf again but 64 should be a
reasonable enough initial growth.

We also no longer silently fail to append to the string when we are
faced with a broken vsnprintf implementation.  On Solaris 9 this
silent failure caused me to no longer be able to execute "git clone"
as we tried to exec the empty string rather than "git-clone".

Brian Downing noticed fast-import can produce tree depths of up
to 6,035 objects and even deeper.  Long delta chains can create
very small packfiles but cause problems during repacking as git
needs to unpack each tree to count the reachable blobs.

What's happening here is the active branch cache isn't big enough.
We're swapping out the branch and thus recycling the tree information
(struct tree_content) back into the free pool.  When we later reload
the tree we set the delta_depth to 0 but we kept the tree we just
reloaded as a delta base.

So if the tree we reloaded was already at the maximum depth we
wouldn't know it and make the new tree a delta.  Multiply the
number of times the branch cache has to swap out the tree times
max_depth (10) and you get the maximum delta depth of a tree created
by fast-import.  In Brian's case above the active branch cache had
to swap the branch out 603/604 times during this import to produce
a tree with a delta depth of 6035.

I had to scratch my head for quite some time figuring out why we
cannot optimize out write_tree() we do when --no-commit option
is given, whose purpose seem to be only to check if the index is
unmerged, with a simple loop over the active_cache[].

So add a comment to describe why the write_tree() is there, and
resurrect the last scripted version as a reference material in
contrib/example directory with others.

There is no reason to forbid a dirty work tree when reverting or
cherry-picking a change, as long as the index is clean.

The scripted version used to allow it:

    case "$no_commit" in
    t)
    	# We do not intend to commit immediately.  We just want to
    	# merge the differences in.
    	head=$(git-write-tree) ||
    		die "Your index file is unmerged."
    	;;
    *)
    	head=$(git-rev-parse --verify HEAD) ||
    		die "You do not have a valid HEAD"
    	files=$(git-diff-index --cached --name-only $head) || exit
    	if [ "$files" ]; then
    		die "Dirty index: cannot $me (dirty: $files)"
    	fi
    	;;
    esac

but C rewrite tightened the check, probably by mistake.

SVN requires that paths be URI-escaped for HTTP(S) repositories.
file:// and svn:// repositories do not need these rules.

Additionally, accessing individual paths inside repositories
(check_path() and get_log() do NOT require escapes to function
and in fact it breaks things).
