If we're worried about the ambiguity/duplication, maybe the proc_info
structure format could be extended to allow multiple match specifications,
or a level of indirection could be introduced.

Dunno whether it's worth it though.  It partly depends on how often we
expect this kind of duplication to occur.


The simplest solution might be to use a macro to avoid duplication in
the source.  This would still create diffstat noise, but it's not
actually fragmentary, so it may be considered OK.

See what other people think, I guess.
