Replying to tigerp:

This has been put in the trunk with a small change. See r327 for the changes.

looking at that patch again, may be a better solution is to use something like

'char about_version_string[sizeof(version_string) + strlen("Version:_\n") + 1];'

just to be aware of buffer overflow.

Little late yesterday:) Not a buffer overflow is the problem (snprintf), a possible truncated string is.
