standard narrow-to-defun but works with Python classes and methods.
With no arg, narrows to most enclosing def/method.  With C-u arg,
narrows to most enclosing class.

last patch to this file: use pathLen, not bufSize, as the initializer.

headers and their continuation lines are parsed.

currently generated by the LaTeX and LaTeX2HTML processes is generated
here as well, making it more flexible in the SGML version.

Reduce the <args> element so that <optional> goes away; just use
square brackets to indicate what's optional.  This makes it easier to
read than the LaTeX, and the processor can do any checking it needs to
in order to make sure it's legit.  Possible shortcoming: DSSSL
processors may need more explicit markup.  Can probably hack around it
for this case, but we'll see.

named header, so that if a message has, e.g. multiple CC: lines, all
will get returned by the call to getaddrlist().  It also correctly
handles addresses which show up in continuation lines.

AdderlistClass.__init__(): Added \n to self.CR which fixes a bug that
sometimes, an address would contain a bogus trailing newline.

Message.getaddress(): In final else clause, added a test for the
character we're at being in self.specials.  Without this, such
characters never get consumed and we infloop.  Case in point (as
posted to c.l.py):

but this won't ever be needed, since the len of a list is still an
int.)

used to deal with the table headings and entries.

An additional flag in the element table is used to indicate elements
which have no "general" content, but which do have subelement
content.  These must be flagged distinctly from empty elements.

This doesn't make a bit of difference on Unix, but apparently on
Windows NT you need write permission before you can set the utime...
