Thank you very much for reviewing the patch, Stefan.

The patch is updated.

- Subexpression 1 is now used for regular expression rule in
  syntax-propertize-rules

- Unused arguments are removed from caller and callee of
  scheme-syntax-propertize-regexp
  
- Changing the third argument of re-search-forward from t to 'move moves
  the point to end if the search does not find closing slash, which is
  ideal.

Attached patches are separated into three. The first one changes only
regular expression part mentioned above. The second one is NEWS update.
The third one removes unused arguments also for
scheme-syntax-propertize-sexp-comment . Please use them as you want.

Also about copyright assignment, this is the first commitment to GNU,
and I have filled out the form and have emailed it to assign@gnu.org .

Thanks
