made configurable via gitcvs.commitmsgannotation.

[PATCH 2/2] cvsserver: change generation of CVS author names

[Fabian Emmes]

CVS username is generated from local part email address.
We take the whole local part but restrict the character set to the
Portable Filename Character Set, which is used for Unix login names
according to Single Unix Specification v3.
