These refs can be anything, but they are most likely useful as
pointing to objects that you know are in the object database but don't
have any regular refs for. For example, when cloning with --reference,
the refs in this repository should be listed as objects that we have,
even though we don't have refs in our newly-created repository for
them yet.

Fetching the objects doesn't actually modify the list in any of the
code paths, so this will allow code that fetches the entire (const)
list of available refs to just pass the list in directly.

  checkout: don't rfc2047-encode oneline on detached HEAD
  filter-branch: Documentation fix.

* maint-1.5.4:
  filter-branch: Documentation fix.

When calling pretty_print_commit, there is an implicit
assumption that passing in a non-NULL "subject" variable
for oneline or email formats means that the output is part
of a subject and therefore "subject" to rfc2047 encoding.
This is not the desired effect when reporting the movement
of detached HEAD.

This eliminates a special case in the show_log() function, to help
simplify the terminator semantics.  Now show_log() always prints a
newline after the log entry when use_terminator is set, even if the log
message is empty.

This change should only affect the --pretty=tformat output, since that
was the only way to trigger this special case.

When using git-cvsimport, the author is inferred from the cvs commit,
e.g. cvs commit logname is foobaruser, then the author field in git
results in:

Author: foobaruser <foobaruser>

Which is not perfect, but perfectly acceptable given the circumstances.

The default git-svn import however, results in:

Author: foobaruser <foobaruser@acf43c95-373e-0410-b603-e72c3f656dc1>

When using mixes of imports, from CVS and SVN into the same git
repository, you'd like to harmonise the imports to the format cvsimport
uses.
git-svn supports an experimental option --use-log-author which currently
results in the same logentry as without that option when no From: or
Signed-off-by: is found in the logentry ($email currently ends up empty,
and hence is generated again).

This patches harmonises the result with cvsimport, and makes
git-svn --use-log-author produce:

Author: foobaruser <foobaruser>

Most users should be using git-gc instead of directly
calling prune. For those who really do want more information
on pruning, let's point them at git-fsck, which goes into
slightly more detail on reachability.

And since we're pointing users there, let's make sure
reflogs are mentioned in git-fsck(1).

The command

  git svn clone (URL of an empty SVN repo here)

works, creates an empty git repository. I can perform the initial
commit there, but then, "git svn dcommit" says :

Use of uninitialized value in concatenation (.) or string at .../git-svn line 414.
Committing to  ...
Unable to determine upstream SVN information from HEAD history

I guess a correct management of the initial commit in git-svn would be
hard to implement, but at least, the error message can be improved.
First step is something like the patch below, and better would be for
"git svn clone" to warn that it won't be able to do much with the
cloned repo.

In get_sha1_basic, we parse a string like

  HEAD@{10 seconds ago}:path/to/file

into its constituent ref, reflog date, and path components.
We never actually munge the string itself, but instead keep
offsets into the string with their associated lengths.

When we call approxidate on the contents inside braces,
however, we pass just a string without a length. This means
that approxidate could sometimes look past the closing brace
and (erroneously) interpret the rest of the string as part
of the date.
