Text events allow %Cfg,bg as decribed in "Theming" on
https://hexchat.readthedocs.org/en/latest/appearance.html?#theming
That section describes mIRC colors 0-15 and local colors 16-31, but
when selecting background colors, the 9 special internal colors are
extremely useful, like %C20,33 will do bright red on the selected
text background color.
As the documentation is on-line, this patch has no doc-change.
Ideally, the color-codes should show in the colored squares in the
preferences color-dialog just as with colors 0-31

Remove old iffed-out version of is_del() as well, as a cleanup step; that change
was for not regarding left and right parens as delimiters. With this change,
mousing over a nickname will underline it even if it contains embedded formatting
data; it used to work with all formatting data but bold and reset; now it
works for all.
