Will do. I assumed Evolution would do something sensible. My mistake :-(

I agree it's wasteful and could be done better however I'm no perl
hacker so I just went for something that was correct and worked. 

The path that is echoed later in the status output is however the CVS
file path which may not be directly related to the actual path in your
source tree. For example I have one status reported as:

$ cvs status src/proj_version
===================================================================
File: proj_version      Status: Up-to-date

   Working revision:    1.1.380.1
   Repository revision: 1.1.380.1       /export/cvsroot/project/src/Attic/proj_version,v
   Sticky Tag:          ATAG (branch: 1.1.380)
   Sticky Date:         (none)
   Sticky Options:      (none)

This makes the matching more than a little problematic.

It depends on how much people that use this script care about performance?

For my part it's a fire and forget script once I've finished my hacking
in a git tree so I don't mind it taking some time. I'm not particularly
minded to dig further in perl to make it faster unless there is a real
clamour - or perhaps someone with a bigger itch and more perl foo can
tackle it. 

In the meantime it does fix a bug in the script so I would say it's
applying.
