Hi,

AFAIK: however you set the syntax of chars:
`forward-same-syntax' will stop at next syntax-change,
for example at a whitespace character inside a comment.

Don't think setting `parse-sexp-ignore-comments'
variable to true will change this, as it is set here that way
and doesn't hinder motion into comments.

Maybe can you tell more, what you are going to achieve,
what the issue behind is?

Cheers
Andreas
