Move my function for fiddling with existentials, mnUtils.EXIN_CONJ_CONV into
the Conv structure under new name EXISTS_AND_REORDER_CONV, and provide
documentation for it. The mnUtils implementation now points back to
the new code (though the behaviour is not identical). Eventually, I think
mnUtils is destined for the bin.

Huge number of check-ins, implementing change to .doc file syntax.
Now the rule for text within braces is that it appears as given, but
that braces must balance. If you want an unbalanced brace, you can use
\lbrace or \rbrace. No existing .doc file uses unbalanced braces.
Also, there is now no need to use \noindent. In fact, doing so
will get you a complaint from the parser. Similarly, use of \ or
{} characters outside of verbatim text blocks will cause griping.
All of the new files have been generated by a parse-then-print process
from the old files, and it's possible there are errors. If you ever
have a spare moment, casting your eye over a random selection of these
might help to find errors.

New versions of docfiles.
