[yandytex] "overcite" package and punctuation

srcltx is known to cause layout problems (look at the docs, and it
warns you to disable the package before final printing).  having said
which, i can't replicate the effect on my tetex system here (i've not
tried on my miktex system).

preliminary hypotheses:

1. spaces in the macros: not likely, given the author, and i don't see
   any sign, looking at the code.

2. current tetex & miktex are using 3.141592, and iirc y&y is using
   3.14159: i can't imagine any of the bugfixes having anything like
   this effect.  similarly, the fact that tetex & miktex are both
   pdfetex engines (if the error was the other way around --
   valid-looking tex code misbehaving on tetex, for example) i might
   suspect the extensions.

3. the srcltx \specials are bothering y&y even worse than they bother
   miktex.

unfortunately, i can't test the sample program on y&y: i've a couple
of duff y&y distros, but no working one.  as karl says, a \tracingall
log file might be interesting.
