[PATCH] cvsimport: strip all inappropriate tag strings

Certain characters such as "?" can be present in a CVS tag name, but git does not allow these characters in tags. If git-cvsimport encounters a CVS tag that git cannot handle, cvsimport will error and refuse to continue the import beyond that point.

When importing CVS tags, strip all the inappropriate strings from the tag names as we translate them to git tag names.

Thank you Junio for the review. I've taken your suggestion and amended my patch to eliminate all the bad strings in ref.c.
