We never did that, no. It's certainly a relevant thing to do, and it would 
be sensible to have a kind of common logic with revision parsing (where a 
caret (^) at the beginning would mean "not"), but at the same time, it's 
not been common enough (read: "I have personally never missed it") to 
actually become an issue.

So I _think_ it would fit fairly well into the current code (just teach 
the stuff that uses "char **pathspec" about that new rule), and it might 
not be too bad. On the other hand, that particular code is pretty dense 
and part of a very core and performance critical subsystem, so unless you 
_really_ want this, you might be better off averting your eyes and just 
ignoring this issue ;)
