Hi!
After upgrading gdb recently gdb ./cc1 etc. asks me to
--Type <RET> for more, q to quit, c to continue without paging--
on start, because the stuff it prints by default + all the

lines don't fit into my 41 line terminal anymore. The following patch
temporarily switches pagination off when printing all those skipped when
stepping messages and restores it back afterwards.
It uses python, but it seems we already unconditionally add to .gdbinit
python import sys; sys.path.append('../../gcc'); import gdbhooks
so I'd hope we don't regress with this anywhere.
Even better would be to tell gdb not to print the skip messages, but it
doesn't have such a support right now.
Tested on x86_64-linux, ok for trunk?

* gdbinit.in: Turn off pagination for the skip commands, restore
it to previous state afterwards.
