Hi.

I committed this corresponding patch.

There is a call to QUIT in recursively_search_psymtabs,
but I like the added symmetry and robustness.

[The astute reader may find that there are already QUIT calls
that can catch ^c's in this case.
E.g., dwarf2read.c calls out to c_print_type (IIRC)
which has a call to QUIT within it. However, there is a problem here
which I still have to address: these QUIT calls can leave symbol tables
partially constructed. Not sure how to fix this yet (I can think of
a couple of ways), and at any rate I like the explicit QUIT calls
that these two patches add.]
