[colm] remove ? * + ( ) and | from allowed chars in position 2+ of literal tokens #75

Closed adrian-thurston closed 4 years ago

Want to promote usage of `,? and other forms in productions. Currently only ] is disallowed in position 2+ of literals. Expand this to ? * + ( ) and |.

Note that () and | are not currently used, but want to add these in the future.

Maybe want to think about also adding single quote literals. Seeing lots of tokens in ragel that are limited by also excluding * from position 2+.
