OK, once I rewrite some more code than a few lines, I will split it
(but now there are really only minor, one-line patches).

Thanks. Still - I don't know if it's still needed at all and what
exactly it was used for (maybe metapost has complained about too long
lines long time ago).

\sometxt is working, only some Aditya's extensions complain. I will
test a bit, try to rewrite some bits and pieces, collect the missing
parts and report back.

You have added the ability to use
\sometxt[something]{abc}
with a background definition of:
\definetextext[something]{\strut}
but I wanted to have two square brackets and Aditya has written a
small patch which does that. Let me explore a bit more in the new mkiv
sources and report back.

Thanks :) I didn't notice any weird behaviour so far, but I'm glad
that it's away before I started complaining about it :) :P
