Segfault in patch

[Bryce Nesbitt]

Is this the proper place for "patch" bug reports?  I see references to a 
"address@hidden" mailing list all over the gnu website, but can't 
find the actual list.

Patch mishandles the program name when parsing arguments:


$ ./patch -Verbose
Segmentation fault

$ patch -Verbose
patch: invalid argument `erbose' for `--version-control or -V option'
Valid arguments are:
 - `none', `off'
 - `simple', `never'
 - `existing', `nil'
 - `numbered', `t'

$ patch --version
patch 2.5.9
