Subject: bug#34805: 25.2; smie-indent-fixindent wrong if comment-start-skip has alternatives
Date: Sun, 10 Mar 2019 16:23:05 +0300

If comment-start-skip contains alternatives smie-indent-fixindent will
construct wrong regexp that appends "fixindent" only to last alternative
and match all other aletrnatives as is.

For example: 

(let ((comment-start-skip "#+\\s *\\|//+\\s *")
      (comment-end-skip ""))
 (concat comment-start-skip
         "fixindent" 
         comment-end-skip)) → "#+\\s *\\|//+\\s *fixindent"

This regexp would match "// fixindent" comments and any comment
that starts with "#", which is wrong. 

I think it should enclose comment-start-skip and comment-end-skip in \\(
\\) to work correctly. Something like:

(let ((comment-start-skip "#+\\s *\\|//+\\s *")
      (comment-end-skip ""))
 (concat "\\(" comment-start-skip "\\)"
         "fixindent" 
         "\\(" comment-end-skip "\\)")) → "\\(#+\\s *\\|//+\\s *\\)fixindent\\(\\)"
