Subject: [PATCH] tg-summary.sh: awksome accelerate --list --verbosely

Use the run_awk_topgit_branches and run_awk_topgit_msg
functions to extremely accelerate the "--list" function
of tg summary.

As a bonus, if the new "--verbose" (or just "-v") option
is also used then include the subjects in the list.

It's now blazingly fast with or without --verbose
whereas before it was okay but nowhere near fast enough
to include the subject lines too.

Also sneak in support for spelling out "-t" as "--terse".

 	This can take a longish time to accurately determine all the
 	relevant information about each branch; you can pass ``-t`` (or ``-l``
 	or ``--list``) to get just a terse list of topic branch names quickly.
+	Also adding ``--verbose`` (or ``-v``) includes the subjects too.
 
 	If no options or arguments are passed, the default is not actually to
 	show ``--all`` branches (that was the default once upon a time).
