Could you answer a question about the gettext API that's come up again
in the context of musl's implementation? The gettext manual documents
that for the message key argument to these functions:
"If the argument is NULL the result is undefined."
https://www.gnu.org/software/gettext/manual/html_node/Interface-to-gettext.html
And it looks like you've treated passing a null argument as a bug in
the past:
https://www.mail-archive.com/bug-gnulib@gnu.org/msg36249.html
It's come up again with GIMP doing it:
https://github.com/void-linux/void-packages/issues/12042
Should we continue to treat this as an application bug and ask the app
maintainers to fix it when it's found? That's my leaning but I want to
make sure we're still on the same page.

Likewise the LI18NUX 2000 specification (p. 39) says
"The msgid argument is a null-terminated string."
And likewise the LSB 3.0
https://refspecs.linuxfoundation.org/LSB_3.0.0/LSB-PDA/LSB-PDA/baselib-dgettext.html
And likewise the Solaris implementation's documentation says:
"The msgid argument is a null-terminated string."
https://docs.oracle.com/cd/E88353_01/html/E37843/gettext-3c.html#REFMAN3Agettext-3c
