Hi, and thanks. That's a good change. I appreciate it.

If a parameter description begins with a '.', this indicates a
"request" for "man" mode output (*roff), so it needs special
handling.
Problem case is in include/asm-i386/atomic.h for function
atomic_add_unless():
* @u: ...unless v is equal to u.
This parameter description is currently not printed in man mode output.
