When speaking of a character, we normally spell this NUL rather than
NULL (which is how we spell a null pointer).
The end-of-sentence period got lost in the rewrite.
Probably not worth a reroll on its own.

In this code-base, it is more common to say:
if (comment_line_char && len && ...
rather than:
if (comment_line_char != '\0' && len && ...
Probably not worth a reroll.

Ditto regarding NUL vs. NULL.
Rather than saying "the second parameter", readers would have an
easier time if you just spelled it out directly (i.e.
"comment_line_char").
The phrase "comments are considered contents to be removed" made sense
before the rewrite, but sounds a bit awkward after the rewrite.
Perhaps rewrite it something like this:
Strip whitespace from a buffer. If comment_line_char is non-NUL,
then lines beginning with that character are considered comments,
thus removed.
May not be worth a reroll.
