[developers] pet-input-chart punctuation-characters

[Bernd Kiefer]

Sorry i didn't follow this thread earlier.

It's correct that PIC does not check for punctuation characters. This
is because PIC was meant for .external. preprocessing, while the
punctuation-chars are used in the internal (simple) tokenizer. If there
are tokens meant to be ignored by cheap in the PIC, the 'constant'
value of the corresponding 'w' XML item should get the value "yes",
which will instruct cheap to skip it.

Since i hope we will agree on a unified input scheme in Spain, i hope
this inconvenience will go away soon.

Best,
        Bernd
