[parser] Error when parameter character is parsed

[Skillmon]

In the parser module, parsing a character with category code 6 will throw an error Illegal parameter number in definition of \pgfparserletter.

Example code:

\documentclass[]{article}

\usepackage{pgf}
\usepgfmodule{parser}
\pgfparserdef{error}{initial}|{\pgfparserswitch{final}}
\pgfparserdef{error}{initial}{\meaning##}{category 6 read}
\pgfparserset{status=true}

\begin{document}
\pgfparserparse{error}#|
\end{document}

I already know how to fix this, but first wanted to ask whether fixing it only for # with category 6 is ok, or should I implement a more robust but slower code that should work for any character of category 6?

Since you are probably the only user of the parser module at all, you can fix it at your discretion.
