BTW, there are a number of places where the old name (hg2git) is still
being used for filenames, et.al, because $PFX is still being set to
hg2git.

All of them.  :-)

Upon doing more investigation, the failure case seems to be if -A is
specified but NOT -s.  Comare:

The date seems to be correctly generated using

	hg-fast-export.sh -s -A ../e2fsprogs.authors -r ../e2fsprogs
	hg-fast-export.sh -s -r ../e2fsprogs
	hg-fast-export.sh -r ../e2fsprogs

It seems to be this combination of options:

	hg-fast-export.sh -A ../e2fsprogs.authors -r ../e2fsprogs

Where all of the dates end up being Jan 1, 1970.
