bug#7058: 24.0.50; Calc:Error in Parser of Syntax Tables

From: Andreas Politz
Subject: bug#7058: 24.0.50; Calc:Error in Parser of Syntax Tables
Date: Fri, 17 Sep 2010 22:14:02 +0200
User-agent: Gnus/5.13 (Gnus v5.13) Emacs/24.0.50 (gnu/linux)

There is something wrong with the Parser of Calcs User Syntax Tables.
The Example given is from (info "(calc) Advanced Syntax Patterns"), so
it should work, but gives an error "Blank tokens are not allowed",
originating in the function `calc-fix-token-name' in calc-prog.el .

Removing the last cond-part in this function is a workaround.

emacs -Q
M-x calc RET
foo ( # { , # , # }? ) := bar(#1,#2)
