[PATCH v4 0/4] Small changes to "list" command

[Bruno Larsen <blarsen@redhat.com>]

I decided to tackle PR cli/30497, and while doing so, Andrew mentioned
that it would also be nice if we could explicitly ask GDB to print the
current location, so I also decided to add that into a series. The first
patch is just some groundwork preparation to make the rest smooth. On
the second pass, I realized that 'list +' isn't properly documented, so
I added it to the docs as well.

After last round of reviews, I changed my approach to fixing cli/30497
to only have a more obvious error message to the end user instead of
jumping back to the current location.

Changes from v3:
 * Reordered patches - now '.' comes first so the UX change can
reference it
 * completely rewrote approach to patch 3
 * made "list ." no longer throw an error when inferior isn't started

Changes from v2:
 * Addressed Eli's comments
 * Added Eli reviews.

Changes from v1:
 * added new arguments to the docs
 * Added patch 4, completely new.
 * Fixed wording, per Eli's suggestions.
