The change in 6cf9397bd6 broke support for
bare repositories. In a bare repo git rev-parse --show-toplevel would
return an empty string and cwd would then be changed to the user's home
directory. In the home directory git rev-parse --git-dir would either
fail or return an unrelated repo.
Problem reported by Ralf Rösch.
Fast-export has traditionally sourced the internal git-sh-setup from
Git, following the release of Git 2.10 this no longer works. Fast-export
only uses the functionality of git-sh-setup for two things: cd:ing to
the git repo dir and setting up the GIT_REPO environment variable. To
future-proof fast-export start doing what we need by hand in
fast-export.
Acknowledgments to Louis Sautier who reported the problem and tested the
fix.
According to the POSIX standard, egrep is an obsolescent equivalent
of grep -E. In fact, the patterns actually being used with egrep do
not require use of extended regular expressions at all, so a plain
'grep' can be used rather than 'grep -E'.
Replace egrep with grep to improve compatibility across systems.
HG tag movement is now supported with this patch.
This patch creates a .git/hg2git-mapping file, which maps
HG revision numbers to HG hashes. Combined with the
.git/hg2git-marks file, which maps HG revisions to GIT hashes,
we can now reprocess all tags at the end of each hg export
operation.
In git 1.6.0, most git tools with a dash in the name will no
longer be installed in $bindir. This patch makes hg-fast-export
use the "git <command>" form so it will work even if "git" is
the only piece of git machinery in the user's PATH.
On the other hand, the "git <command>" form does not help for
sourcing a shell script (with "."). So use the full path to
source "git-sh-setup".

Given a hg revision to reset to, these scripts get the latest changes
per hg branch and print git SHA1. The user then needs to manually reset
branches as needed, tune the state file and can re-import things again.
