Subject: Make specification of CVS module to convert optional.
X-Git-Tag: v0.99~71^2^2~6
X-Git-Url: https://git.octo.it/?p=git.git;a=commitdiff_plain;h=f9714a4a0cd4ed0ccca3833743d98ea874a2232d

Make specification of CVS module to convert optional.

If we're inside a checked out CVS repository, there is
no need to explicitly specify the module as it is
available in CVS/Repository.
Also read CVS/Root if it's available and -d is not specified.
Finally, explicitly pass root to cvsps as CVS/Root takes
precedence over CVSROOT.
