[hlx] smart quotes and dashes (patch)

[Christopher L. <le...@co...>]

Hi all,

I started playing with HyperLaTeX a few days ago, and only checked out
the mailing list just now.  I hope to use it to create course
materials that are as beautifully typeset on paper as they are
well-designed and navigable online.

One of the first things I hacked in was generating proper left and
right quotes from TeX's  `` and '' as  well as em and en dashes from
--- and --.  (Only afterwards did I see Harald Soleng's post for this
feature request.)

Unfortunately, I did this by hacking it into hyperlatex.el, before I
discovered that \HlxEval could probably do the trick within a .hlx
extension package.  At any rate, I'll post the diff to hyperlatex.el
here, if someone wants to try it.  At some point later, I will try to
re-implement it as a .hlx, if you think that's more appropriate.

Best wishes,
Chris
