WinCVS doesn't copy the template file specified by rcsinfo to any of the CVS subdirectories, thus the commit-template option doesn't work (it doesn't show the template contents, and it produces the following error message: "Template file not found. You need to setup Template using rcsinfo file. Please refer to CVS documentation for more details."
After copying the file myself, things work o.k.
However, all lines prefixed with "CVS:" still show up in the log file.
Linux CVS works fine.
