[RFA] info (break|watch|trace), use get_number_or_range

[Michael Snyder <msnyder@vmware.com>]

[-- Attachment #1: Type: text/plain, Size: 208 bytes --]

I've always thought that info break should accept a list and/or a range.

Since this is an enhancement, I'll wait for review.  OK?

Eli, I'll wait on the docs change until we agree what it should look like.

	* breakpoint.c (breakpoints_info): Re-implement using 
	get_number_or_range.
