The idea looks sensible to me, but I think you've made a mistake in the
regular expression syntax. The character '-' has to appear immediately
after the open bracket, otherwise it's taken to be the punctuation in a
range such as "A-Z". So the character class
[+-MmZzLlHhVvCcSsQqTtAa0-9,.Ee\n ] will match (at least) any character
between '+' and 'M'.

If you start the brackets with [-+Mm...] instead of [+-Mm...] then I
think it does what you intended.


I am not sure if this will update the tracker as Simon would have to have the correct rights (he only contributes occasionally like this so probably won't be interested in general LP development) the point is that I may have to cut/paste his reply into the tracker if this is the case so others can follow.
