Tweak the position of spaces between function invocations and arguments
so that the expansion of mediawiki-specific functions (`\Rho`, etc) is
consistent with how spacing is added to normal function invocations.
This helps ensure that `texvc`/`texvccheck` is idempotent -- that is,
that it can parse what it emits, and render it without change.

The \overbrace, \overleftarrow, \overleftrightarrow, \overline,
\overrightarrow, \underbrace, \underline, \widehat, and \widetilde
commands take a single mandatory argument. Move \overbrace and
\underbrace to the fun_ar1nb list, since they handle trailing
subscripts and superscripts specially. Move the other functions to
the fun_ar1 list.

The \AA and \textvisible space commands aren't valid in math mode.
Surround them with \mbox so that we switch to text mode before
emitting them.

It is impossible to take the empty alternative for this production,
since any input which matches `litsq_aq` would instead match `lit_aq`
if the empty alternative is used. In addition, there is no action
clause for the empty alternative, so it wouldn't typecheck if the
empty alternative was possible.
This has no effect on the generated parser, but clarifies the grammar
(and makes ports easier!).

texvc had several tasks in the past:
1 checking the input
2 convert MediaWiki custom syntax to standard LaTeX
3 run LaTeX
4 convert dvi2png
This change provides a simplified version that performs
only steps 1+2. This is required to avoid security problems
with tools like MathJax, especially if these tools are
run at the server-side.
