 You will be (un)happy to know that every version since 19.11 has
done
 this.

 And if you move the `(' off the BOL, everything works fine.

 The problem is not in C-mode per se, but deep in the depths of
 find_start_of_comment().

 Line 526 of syntax.c decides that a character code type of Sopen at
 the beginning of the line means we are done looking, and the function
 itself will then leave you at the end of the comment.

 I guess the thing to do is figure out why the assumption at line 526
 is there.  I guess I could remove it, rebuild, and see what breaks.

 I will. 
I did.  It works correctly, and everything else seems to be fine.

I have a feeling that this is very old and stale code that was cut and 
pasted from a older function that used to search backwards for the
beginning of strings.

I do not know whether this patch should wait until 21.1, since it may
be thoroughly wrong.  However, it looks to my eye like I just got rid
of some obsolete code.
