Wildcard permits more than often intended in argument lists

[edneville]

Users often expect glob-like behaviour from sudoers rules and are surprised when arguments don't behave that way. PR #10 adds regex matching to argument lists. The only work around I know of to prevent * matching other arguments adds complexity and is awkward and doesn't work well with path traversal, that requires a second negation, like so:

user ALL=ALL /bin/cat /var/log/*
user ALL=ALL !/bin/cat /var/log/* *
user ALL=ALL !/bin/cat /var/log/*..*

I feel overall that the problem would be lessened greatly with this patch.

This will close bug 578.
