git -> hg conversion script
contrib/convert-repo changes:
- do not print verbose output so that error messages are seen more easily
- Output the date as integer and not as floating point number.
- Do not require a ".git" subdirectory to work on, but use the GIT_DIR
environment var to specify the git repository.
Change is otherwise compatible to the current version and I have tested it
by converting the kernel and several git respositories from kernel.org.
(Btw, the udev test dir contains a /sys dir with entries which should not
be normal dirs and not be normal files. ;-)
Thanks again for mercurial,
Florian La Roche
