To the best of my knowledge, Mac OS X cannot assign a file to an application based on a filename prefix. It can only do so based on a filename extension.
And for viewing them: How do you highlight diff files?
Currently, TextWrangler uses no syntax highlighting on diff files. This is better than the incorrect syntax highlighting that could result by trying to highlight based on the rules of the diffed file. There is such a thing as a multiline comment, or a multiline string. It's possible a diff might include either the opening or closing quote or comment mark, but not the other one, which would result in chaotic highlighting. I have seen this before.
In the future, I might write my own syntax highlighting rules for diff files which could, for example, color lines beginning with a + or - in green and red, respectively, similar to what we see in the Trac repository browser or the commit mails.
FWIW... TextMate does highlighting of diff files if the file is named '*.diff' or if you explicitly select diff as the mode. It does not attempt to do _syntax_ highlighting _within_ a diff -- so no C or Perl or whatever syntax highlighting. - boyd Boyd Waters Scientific Programmer National Radio Astronomy Observatory Socorro, New Mexico
