Hi,
(1) doc/indent.texi lines 1582 and 1584 are identical: you are listing
--gettext-strings twice. The second one probably should read
--no-gettext-strings, right?
(2) The documentation should explain why --gettext-strings is important
and recommended. Namely, when a message has comments for translators,
the 'xgettext' programs recognizes such comments only when they
appear at most one line apart. So, after 'indent' has added an
additional line break, they are no longer recognized. See:
$ cat foo1.c
/* TRANSLATORS: the argument is non-negative. */
printf (_("speed: %g knots"));
$ cat foo2.c
/* TRANSLATORS: the argument is non-negative. */
printf (_
("speed: %g knots"));
$ xgettext -o - -k_ -cTRANSLATORS foo1.c
