This is insufficient, since my mail client generates something
completely different of "FW" on forwarding and some other software
authors think it's a good idea to replace "Re:" with its "translation"
to the users' language.

I agree we could/should drop the colon form.

OK.  How about the spaces between "PR" and the number?

The current regexp contains the fragment

  ([-a-z0-9_+.]*[:/][ \t]*([0-9]+))

that matches "PR/" automatically.  Dirk's point is to include "PR"
without the slash as well.

    PT> By the way, refile-pr was written for 4.

Very well. :-)

Well, to summarize, I suggest the following:

- Not to try to match "re", "fw", etc. and simply look for a substring
  as stated below.

- Accept "\<CATEGORY/NUMBER" where CATEGORY is a valid category name and
  PR NUMBER is present in CATEGORY.

- Accept "\<PR[ \t/]*NUMBER" where "PR" must be all capitals and NUMBER
  corresponds to an existing PR number.

Would it serve the purpose in an acceptable way?
