1) Fixed a highlight-related PSGML bug that caused errors when there
was a processing instruction before the DOCTYPE declaration (this
is a big problem in XML, for obvious reasons).
2) Fixed PSGML's support for the `sgml-system-path' variable, and set
the initial value of the variable automatically from the
environment variable SGML_SEARCH_PATH (as used by NSGMLS), if
present.
The second one turns out to be a very useful change. If you do
something like
(setq sgml-system-path '("." "/usr/local/lib/sgml/global"))
or (for NSGMLS support as well)
export SGML_SEARCH_PATH
SGML_SEARCH_PATH=".:/usr/local/lib/sgml/global"
and then put the file `spec.dtd' in /usr/local/lib/sgml/global, then
you can always reference that DTD with a relative URL as if it were in
the current directory (NSGMLS has always allowed this, but it wasn't
fully implemented in PSGML). That means that
<!DOCTYPE spec SYSTEM "spec.dtd">
works, and you no longer have to copy the DTD file into every
directory that uses it. I've also fixed the parsing of environment
variables so that ';' can be the separator in DOS/Windows, though I
haven't tested that part yet.

Have fun!
