*See 'ecolor': 9 blue (like keywords), 8 black, 6 dark cyan (strings), 1 red.
*The sort order is significant, anything already handled above does not work,
*e.g., most strings, identifiers, keywords, and comments are already colored.

* logical NOT U+00AC is valid (assuming Latin-1 or similar here, not UTF-8):
 text ¬           alternate 8
* red for comma, tricky at the end of a line
 text ,           alternate 1
* red for backtick + obsolete:
 class [`^@#$]    alternate 1
* red controls and non-ASCII (outside of strings and comments)
 class [~!-~]     alternate 1
