Choosing good keywords for tickets

Trac can search the full text of tickets, so adding a keyword that already occurs in another field doesn't help for general searching. If we standardise the use of certain keywords, however, it could make finding certain specific types of ticket much easier. This, then, is a suggested list of keywords that we might like to standardise.

Keyword	Meaning
haspatch	The ticket has a patch attached which the submitter believes will fix the bug or implement the enhancement.
maintainer	The ticket contains a patch from the port's maintainer, and can thus be acted upon immediately.

i386/x86_64/ppc/ppc64	The ticket is only applicable when using the indicated build_arch
LP64	The ticket is only applicable when building for a 64-bit arch
