Good to know!  So, I studied 'luaL_traceback' in 'lauxlib.c' in Lua and
made the regular expression more precise.  No more mis-classification!

Ditto; I made other expression more precise as well!

/Note:/ I rebased on top of 'master' (and so the 'omake' patch).

See the new patch, with more precise regular expressions, attached
below.  While on it, I also added support for stack frames with no line
number, as per Lua source code.  Lastly, I added a NEWS entry, as well
as, improved the commit message a bit.

How about now? :)
