RFA: documentation change for ambiguous linespec patch

This needs a doc review.

To my surprise, the ambiguous linespec change mostly makes gdb accord
better with the existing documentation.  So, I did not need many changes
to the documentation.

Here is what I propose.

	* NEWS: Document ambiguous linespec change.

	* gdb.texinfo (Set Breaks): Update for new behavior.

 *** Changes since GDB 7.3.1
+* GDB now handles ambiguous linespecs more consistently; the existing
+  FILE:LINE support has been expanded to other types of linespecs.  A
+  breakpoint will now have locations at all the matching points in all
+  inferiors, and locations will be added or subtracted according to
+  inferior changes.
 * GDB now allows you to skip uninteresting functions and files when
   stepping with the "skip function" and "skip file" commands.
