Is there a way to make "git cvsimport" create branches in git for any
branches it encounters in the CVS repository?

All my imports so far show just a linear line of development, and CVS
branch information seems lost.

Best regards,

Heh. I was just preparing mail about the same problem.
It seems that git-cvsimport-script really don't likes branches in CVS.
I have attached simple script that demonstrates this.
On my machine it gives:
=============================
snake@home2:/tmp$ ./testscript
cvs checkout: Updating project
cvs add: scheduling file `a' for addition
cvs add: use `cvs commit' to add this file permanently

=============================
Is it a planned behaivoir or cvsimport script were just recently broken?

Umm, exactly what did you do to visualize that? "gitk origin" obvioously
shows only one branch, because CVS doesn't have merge infe. Use
"gitk $(cat .git/revs/heads/*)" to show everything.

s/v/f/

I see. Thanks for pointing out. Umm... is there  a  way  to  manually
adjust  this  later?  I  can  identify the specific PatchSet(s) which
merge my CVS branches back into the trunk.

But it does not, at least in some cases.
See my previous mail:
http://marc.theaimsgroup.com/?l=git&m=112159075029007&w=2
It have simple script attached that reproduces the problem.

Ouch. It was all me. I have lost -A flag.

Sorry for noise again.
I have found two bugs in cvsps that results in the wrong import to git.
I tried to contact developer but it seems that his mail have no mailserver 
ATM. Since he has made some changes for git already - probably someone on 
this list have his new contact. Please tell me it or forward my mail to him. 
Thanks.

For the curious, here are the bugs:
1) some branches fork off too late - cvsps shifts brahches starts forward to 
the future
Example:
http://www.penza-gsm.ru/snake/testscript

2) some branches are not detected at all, not recorded as patchsets and 
consequently not imported into git.
Example (branch "old"):
