but the only implementation of regexp + something-like-TeX-escaped-p I
was able to make fails with
\$$something$
:-(
What it does is the following:
- search for `$' or `$$';
- check whether there is an even number of escapes before the found
string, but this doesn't make sense with `$$' since only the first
dollar sign is escaped.
It could be improved with something like this:
a) search for `$';
b) check whether there in even number of escapes before it;
c) if b)-test is positive: check if there is an additional dollar
following the first `$';
d) if b)-test is negative: restart from a).
Can this work?
