Re: Difficult macro parameters - removing the implicit document tag

It's incredible the number of hours I spent over the last week because of
the difficulty in getting texmacs to remove the default document tag from a
macro definition/invocation.

I can trick it into not happening with: \compound ENTER do-something TAB
and then enter arguments with TAB for each one, then I get all on one line:
<do-something|<arg|x>>

But if I type: \do-something ENTER
and then enter arguments, I get:
<\do-something>
  <arg|x>
</do-something>

which wraps my argument in an implicit document tag

That makes me very sad.

But I learned so much interesting stuff that should never need to be
learned doing this :-)
