top: existing 'Inspect' pipe feature now more flexible

Browse Source 
Currently, it isn't possible to establish an 'Inspect'
pipe that relies on SIGINT to end. That's because this
signal will also end the parent process (top) as well.

So this patch will temporarily ignore that signal when
processing any 'Inspect' pipe, allowing one like this:

. pipe ^I Trace Calls ^I /usr/bin/strace -r -p %d 2>&1
