Is there really a reason to describe them all in one place?  I'm not
sure.

How about if we make a mode which will do that editing for us?  E.g.,
imagine that we have a file whose name is recorded in the debug info
as /a/b/c/d/e/z.c, and some search path.  Then GDB would first try the
literal /a/b/c/d/e/z.c, then, for each directory X that's mentioned
in the search path, it will try these:

   X/z.c
   X/a/b/c/d/e/z.c
   X/b/c/d/e/z.c
   X/c/d/e/z.c
   X/d/e/z.c
   X/e/z.c

How does this sound?
