Hi,
if `(forward-comment 1)' is called with some empty lines
ahead followed by non-commented code, it returns nil
but travels buffer like
`(skip-chars-forward " \n")' would do.
Also it stops at next text, but doesn't reach next existing comment.
If not inside or in front of a comment,
(forward-comment 1) should behave like `search-forward',
or just return nil, if not successfully.
IMHO should be implemented a consistent design how to behave,
if a call to a move function don't find it's object.
Search-forward and forward-word differ here for example.
Thanks
Andreas

It is behaving as documented:
Stop scanning if we find something other than a comment or whitespace.
Set point to where scanning stops.
If COUNT comments are found as expected, with nothing except
whitespace between them, return t; otherwise return nil.
