Fix a rare segfault in syntax.c

* src/syntax.c (Fforward_comment): Prevent the loop for COUNT < 0
from going outside the valid range of character/byte positions.
(Bug#43499)

* doc/lispref/syntax.texi (Syntax Class Table): Mention the
"comment-fence" and "string-fence" as alternative names of 2
syntax classes.
