Hi Arash,

Many for your feedback.

Indeed, I had in mind (but forgot to write) that I left the manual doc
as a stub until the general behavior was approved.  I've now attempted
a proper manual entry.

Agreed that this is clearer.

The relevance of TeX-fold-begin-display and TeX-fold-end-display is
that it is only through these functions that
TeX-fold-begin-end-spec-list "plugs in" to the user option
TeX-macro-spec-fold-alist.  If the user modifies that option to have
different display specifiers for begin and end, then
TeX-fold-begin-end-spec-list becomes irrelevant.  I've tried to make
this point clearer in the updated doc, but any further feedback is
welcome.

I had internalized that "mandatory arguments" and "arguments in
braces" were the same thing in LaTeX, but could be mistaken on this.
I've adjusted this docstring (and related ones) to say simply
"mandatory macro arguments", which seems consistent with what is
written elsewhere in tex-fold.el, but would welcome other suggestions.

QUESTION: should these features be considered LaTeX-specific, hence
added to LaTeX-fold-macro-spec-list and perhaps moved from tex-fold.el
into either latex.el or some new file latex-fold.el?  I personally
find the current organization reasonable, but am open to suggestions
here.

Thanks, best,

Paul
