Changes in version 3.16c

This file incorporates the changes from version 3.16 that previously
appeared in file CHANGES-3.16a and -3.16b; new changes for this
release (3.16c) are marked with a plus ("+") sign.
 

New answer:
 +Label isdef:    "is this command defined?" tests
  Label optionclash: clashing package options error in LaTeX

Revised answers:

 +Label citeURL:  provide a list (rather than a bunch) of alternative
                  styles, mention babelbib
  Label ECfonts:  reword discussion of mathematics and EC fonts (i.e.,
		  emphasise that there's no direct relation)
  Label filename: extend macro definitions, hopefully expanding the
                  usefulness and usability of the answer
  Label hyperdupdest: other sources of the error than repeated pages
  Label minitoc:  corrected error in q-minitoc code, tidy comments
  Label minxampl: include the word "minimal", since it's a common search term

Bugfixes:
  Label cmdstar:   part of the example code was just wrong
  Label enumerate: unclarity in text caused by a typo
  Bug in "introduction=yes" HTML code corrected
  Label atsigns:   mark-up error caused curious HTML output (editorial
		   improvement too)
 +Release dates are now represented in ISO format (yyyy-mm-dd) --
  previously we used the LaTeX format, using solidus instead of hyphen

Future releases:
  Despite missing the nominal "end August 2006" delivery (through an
  unfortunate combination of events), I'm aiming to maintain the
  stream of (approximately) monthly "bugfix" releases.  There are no
  current plans for a major release, though work on the new web-based
  version continues.
