gettext man pages have old date at bottom (May 2001)

[Gavin Smith]

I was reading a man page for gettext(3) and I wanted to know where
the page came from.  I scrolled to the bottom of the page and there was:

GNU gettext 0.22.5                 May 2001                         GETTEXT(3)

I downloaded gettext-0.23 and checked that the string "May 2001" is also
present in several man page sources:

./gettext-runtime/man/bindtextdomain.3.in:.TH BINDTEXTDOMAIN 3 "May 2001" "GNU 
gettext @VERSION@"
./gettext-runtime/man/textdomain.3.in:.TH TEXTDOMAIN 3 "May 2001" "GNU gettext 
@VERSION@"
./gettext-runtime/man/ngettext.3.in:.TH NGETTEXT 3 "May 2001" "GNU gettext 
@VERSION@"

Can I suggest that the update date is updated along with the version number?
This could give some reassurance that the documentation is up to date.

These pages have been altered since 2001, for example there is a ChangeLog
entry from 2024-11-19 mentioning some of these pages.

For gettext, there is some confusion about where its documentation is
("libc" Texinfo manual from glibc, "gettext" Texinfo manual, man pages from
gettext, also man pages from "Linux man pages" which come from gettext), with
some of the manuals more detailed or comprensive than others.  Having correct
dates could reduce the confusion slightly.
