[PATCH] git-p4.py: add support for filetype change

[PATCH] git-p4.py: add support for filetype change

[Romain Picard]

After changing the type of a file in the git repository, it is not possible to
"git p4 publish" the commit to perforce. This is due to the fact that the git
"T" status is not handled in git-p4.py. This can typically occur when replacing
an existing file with a symbolic link.

The "T" modifier is now supported in git-p4.py. When a file type has changed,
inform perforce with the "p4 edit -f auto" command.

Romain,

Thanks for looking at this. It looks like a reasonable change.

Do you think you could add a unit test as well?

Thanks
Luke

Yes, I will look at the existing tests to see how to add some new ones.
