Subject: [PATCH] cat: Fix GCC 10 warning.

I believe this warning is bogus, but simply initializing the local
variable is enough to avoid it.

log.c: In function 'do_log':
log.c:390:7: error: 'comm_len' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  390 |       printf (" %.*s", (int) comm_len, comm);
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

(cherry picked from commit 4e199494c41d3240aa5c0708887b7a7513c6b6f2)
