4d23660e (describe: when failing, tell the user about options that
work, 2009-10-28) forgot to update the shortcut path where the code
detected and used a possible exact match.  This means that an
unannotated tag on HEAD would be used by 'git describe'.

Guard this code path against the new circumstances, where unannotated
tags can be present in ->util even if we're not actually planning to
use them.

While there, also add some tests for --all.

(and probably others) mistakenly thinks variable 'right' is used
before assigned.  Work around it by giving it a fake initialization.

git-svn has the following rule to detect the SVN base for its
operations: find the first git-svn-id line reachable through
first-parent ancestry.  IOW,

  git log --grep=^git-svn-id: --first-parent -1

Document this, as it is very important when using merges with git-svn.

We parse unhandled.log files for empty_dir statements and make a
best effort attempt to recreate empty directories on fresh
clones and rebase.  This should cover the majority of cases
where users work off a single branch or for projects where
branches do not differ in empty directories.

Since this cannot affect "normal" git commands like "checkout"
or "reset", so users switching between branches in a single
working directory should use the new "git svn mkdirs" command
after switching branches.
