[bug #65474] spurious "warning: unbalanced 'el' request" when formatting zic(8) from TZDB project

[Dave]

Follow-up Comment #5, bug #65474 (group groff):

I agree with Paul that -ww is not intended as a style check.  But I further
contend that this is not subpar style.

There is nothing ambiguous about the code in Paul's original example, either
to a human reader who understands basic if/then/else syntax, or to a machine
parser (theoretically, and seemingly in practice, except that something is
confusing groff's parser into emitting a spurious warning).  Braces are not
required for this construction in C.

#include <stdio.h>
main() {
  if (1 == 2)
    puts("Weird");
  else if (2 < 1)
    puts("Also weird");
  else puts("Normal");
}

When "if" statements are nested without braces, there can be ambiguity about
which one an "else" applies to.  But there is none here.
