	I'm sorry, I was referring to your statement which I cut out from 
the top, which was:

-> > -> unrelated to the widget). Using lots and lots of tags could double
                                                 ^^^^^^^^^^^^^^^^^^^^^^^^^

	If every on/off pair of tags takes 80 bytes, and you consider a
random line of syntax-highlighted source code:

  if (active_window_stack)

	...and "if", "("/")", and "active_window_stack" each have their
own color, that's 4 * 80 bytes per on/off tag pair, so 320 additional
bytes on top of 25 bytes worth of text--not counting the additional
line/tree overhead used to store the text.

	I'd consider that a memory hog.  Am I missing something?

	Somebody posted a Glib-ized regex to the list a few weeks ago, and
it got some feedback and went through a couple of iterations.  Is there
any reason not to add it to Glib?  I think it would be very useful to
have.

	I've seen several emails (including today) between Tim and Owen
discussing different filenames for concurrent installs; since they haven't
finished that work yet, I assumed it was best to wait until they had it
straightened out.

	Is there are How-to/FAQ about developing with concurrent versions?
How do you have your environment set up?  What does your /etc/ld.so.conf
look like?  What option must I give to ./configure?  Etc.

	I can't afford to hose my working system.
