diff --exclude format

[Matthew Watson]

Thanks for the pointer to that obvious doco I overlooked!

path: would be even better, but it seems to drop trailing '/'s

hg diff -r 0 .hgignore --exclude path:.hgignore/

return nothing, whereas

hg diff .hgignore -r 0 --exclude 're:\.hgignore/.*'

gives me what I want: the diff for .hgignore only.

If a path was a dir but got removed and a file created with the same
name, I don't want to know about all the files in the dir, just the
diff for the exact path match.

FYI: this is for atlassian FishEye interrogating the repo.
