(Please remember to move this to the 7.11 section.)

Spurious double period.

Remove useless return.

AFAICS, these two are unused now.  Remove them.

This "$parameters" here will end up producing redundant
test message, given the with_test_prefix already includes
that info.  Remove it:

   gdb_test "where" "No stack." "no inferior"

Please take look at the resulting gdb.sum file, and check for
other similar cases and fix them.

The code changes are OK with the above issues addressed.

I think you still need to get an OK from Eli, though.

Thanks,
