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

HGMERGE(1)
==========
Matt Mackall <[e-mail]>
v0.1, 27 May 2005

NAME
----
hgmerge - default wrapper to merge files in Mercurial SCM system

SYNOPSIS
--------
'hgmerge' local ancestor remote

DESCRIPTION
-----------
The hgmerge(1) command provides a graphical interface to merge files in the
Mercurial system. It is a simple wrapper around kdiff3, merge(1) and tkdiff(1),
or simply diff(1) and patch(1) depending on what is present on the system.

hgmerge(1) is used by the Mercurial SCM if the environment variable HGMERGE is
not set.
