And besides, it has been the default rendering of the .Ex macro
for more than 15 years (Werner Lemberg, 2001):

http://git.savannah.gnu.org/cgit/groff.git/commit/tmac/doc.tmac?id=e345bdfac5bf9ca180445e93afe0a473c668ed8f

schwarze@isnote $ echo .Ex -std | mandoc -mdoc -Tascii | grep exits            
The utility exits 0 on success, and >0 if an error occurs.
schwarze@isnote $ echo .Ex -std | groff -mdoc -Tascii 2>/dev/null | grep exits 
The utility exits 0 on success, and >0 if an error occurs.
schwarze@isnote $ export PATH=/usr/local/heirloom-doctools/bin/:$PATH
schwarze@isnote $ echo .Ex -std | nroff -mdoc | grep exits         
The  utility exits 0 on success, and >0 if an error occurs.

The wording was originally intoduced by Cynthia Livingston
on July 24, 1990 for 4.3BSD-Reno, when she set out to rewrite the
whole corpus of BSD manuals in the version 2 predecessor of her
new mdoc(7) language to replace the AT&T Copyright-encumbered man(7)
versions:

schwarze@isnote $ cd /co/4.3BSD-3Reno
schwarze@isnote $ grep -F .Dd $(grep -RFl 'exits 0' *)
