You're right, thanks for the patch, i will probably try to include them.

Probably, because hints are scheduled for a rewrite which would get rid
of the hintchars variable. Reason is that for a link "more" it would
make more sense to have "MO" as the tag then "JK" e.g.

However, the rewrite is a little on hold now, so i might put in you fix
for now as it is quite short anyway.

I also thought that it might be simpler to just check if the hint
mathces /[a-zA-Z]/ to see if it contains alphachars.

Thanks for the patch tough!
