I didn't have a chance to test the off-by-default minimize-url
stuff enough before, but it's quite broken for people passing
the --trunk/-T, --tags/-t, --branches/-b switches to "init" or
"clone" commands.

Additionally, follow-parent functionality seems broken when we're
not connected to the root of the repository.

Default behavior for "traditional" git-svn users who only track
one directory (without needing follow-parent) should be
reasonable, as those users started using things before
minimize-url functionality existed.

Behavior for users more used to the git-svnimport-like command
line will also benefit from a more-flexible command-line than
svnimport given the assumption they're working with
non-restrictive read permissions on the repository.

I hope to properly fix these bugs when I get a chance to in the
next week or so, but I would like to get this stopgap measure of
reverting to the old behavior as soon as possible.

When sorting directory names by depth (slash ("/") count) and
closing the deepest directories first (as the protocol
requires), we failed to put the root baton (with an empty string
as its key "") after top-level directories (which did not have
any slashes).

This resulted in svnserve being in a situation it couldn't
handle and caused a segmentation fault on the remote server.

This bug did not affect users of DAV and filesystem repositories.

The todo list at the end of the user manual says that something must be
said about .gitignore. Also, there seems to be a lack of documentation
on how to choose between the various types of ignore files (.gitignore
vs. .git/info/exclude, etc.).

This patch adds a section on ignoring files which try to introduce how
to tell git about ignored files, and how the different strategies
complement eachother.

The syntax of exclude patterns is explained in a simplified manner, with
a reference to git-ls-files(1) which already contains a more thorough
explanation.

The embarassing history of this tutorial is that I started it without
really understanding the index well, so I avoided mentioning it.

And we all got the idea that "index" was a word to avoid using around
newbies, but it was reluctantly mentioned that *something* had to be
said.  The result is a little awkward: the discussion of the index never
actually uses that word, and isn't well-integrated into the surrounding
material.

Let's just go ahead and use the word "index" from the very start, and
try to demonstrate its use with a minimum of lecturing.

Also, remove discussion of using git-commit with explicit filenames.
We're already a bit slow here to get people to their first commit, and
I'm not convinced this is really so important.

gitattributes.txt says, of the crlf attribute:

 Set::
    Setting the `crlf` attribute on a path is meant to mark
    the path as a "text" file.  'core.autocrlf' conversion
    takes place without guessing the content type by
    inspection.

That is to say that the crlf attribute does not force the file to have
CRLF line endings, instead it removes the autocrlf guesswork and forces
the file to be treated as text.  Then, whatever line ending is defined
by the autocrlf setting is applied.

However, that is not what convert.c was doing.  The conversion to CRLF
was being skipped in crlf_to_worktree() when the following condition was
true:

 action == CRLF_GUESS && auto_crlf <= 0

That is to say conversion took place when not in guess mode (crlf attribute
not specified) or core.autocrlf set to true.  This was wrong.  It meant
that the crlf attribute being on for a given file _forced_ CRLF
conversion, when actually it should force the file to be treated as
text, and converted accordingly.  The real test should simply be

 auto_crlf <= 0

That is to say, if core.autocrlf is falsei (or input), conversion from
LF to CRLF is never done.  When core.autocrlf is true, conversion from
LF to CRLF is done only when in CRLF_GUESS (and the guess is "text"), or
CRLF_TEXT mode.

Similarly for crlf_to_worktree(), if core.autocrlf is false, no conversion
should _ever_ take place.  In reality it was only not taking place if
core.autocrlf was false _and_ the crlf attribute was unspecified.

As noted by Johan Herland, git-archive is a kind of checkout and needs
to apply any checkout filters that might be configured.

This patch adds the convenience function convert_sha1_file which returns
a buffer containing the object's contents, after converting, if necessary
(i.e. it's a combination of read_sha1_file and convert_to_working_tree).
Direct calls to read_sha1_file in git-archive are then replaced by calls
to convert_sha1_file.

Since convert_sha1_file expects its path argument to be NUL-terminated --
a convention it inherits from convert_to_working_tree -- the patch also
changes the path handling in archive-tar.c to always NUL-terminate the
string.  It used to solely rely on the len field of struct strbuf before.

archive-zip.c already NUL-terminates the path and thus needs no such
change.

Helping a couple people set up public repos recently, I wanted to point
them at this piece of the user manual, but found it wasn't as helpful as
it could be:

	- It starts with a big explanation of why you'd want a public
	  repository, not necessary in their case since they already knew
	  why they wanted that.  So, separate that out.
	- It skimps on some of the git-daemon details, and puts the http
	  export information first.  Fix that.

Also group all the public repo subsections into a single section, and do
some miscellaneous related editing.

Move howto/using-topic-branches into the user manual as an example for
the "sharing development" chapter.  While we're at it, remove some
discussion that's covered in earlier chapters, modernize somewhat (use
separate-heads setup, remotes, replace "whatchanged" by "log", etc.),
and replace syntax we'd need to explain by syntax we've already covered
(e.g. old..new instead of new ^old).

The result may not really describe what Tony Luck does any more.... Hope
that's not annoying.

There seems to be a perception that the howto's are bit-rotting a
little.  The manual might be a more visible location for some of them,
