Lobbying for -p1 diffs

Robert Collins, and lo! it spake thus:

Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|=== modified file 'foo/bar'
|--- foo/bar    
|+++ foo/bar    
--------------------------
Patching file foo/bar using Plan A...

% cat foo/bar
hi
% patch -v
Patch version 2.1


Per the manpage:
    [...] and not specifying -p at all just gives you "blurfl.c",
    unless all of the directories in the leading path
    (u/howard/src/blurfl) exist and that path is relative, in which
    case you get the entire pathname unmodified.
