[PATCH] Make git-cvsexportcommit "status" each file in turn

Hi,

It turns out CVS doesn't always give the status output in the order requested. According to my local CVS gurus this is a known CVS issue.

The attached patch just makes the script check each file in turn. It's slower but correct.

I also slightly formatted the warn output when it detects problems as multiple line wraps with long file paths where making my eyes bleed :-)
