Failures of unit tests with old versions of git executable

[Jun Omae]

According to TracGit, Trac supports git 1.5.6 and later.

We try to maintain backward compatibility with versions of Git as old as 1.5.6, up to the latest. Better use a recent version however.

However, in fact unit tests failed with both 1.5.6.5 and 1.6.6.3.

Git	Results
1.5.6.5	FAILED (failures=24, errors=12)
1.6.6.3	FAILED (failures=6, errors=12)
1.7.12.4	OK
1.8.5.5	OK
1.9.4	OK
2.0.4	OK
2.1.0	OK

We should fix the failures, otherwise update supported versions in TracGit. I'll investigate it….

Proposed changes can be found in jomae.git@t11715. Only unit tests have this issue. The following lead this issue;

• git init accepts an extra argument since 1.6.5.
• git commit accepts --date option since 1.7.0.

I'll push to 1.0-stable later.

Unit tests pass with Git 2.1.0, which is released on 2014-08-15.
