Why doesn’t the ‘patch-shebangs’ phase do its job?  Could
‘patch-shebang’ be used instead of ‘substitute*’?

Yeah.

OK.  I suppose Solfege also supports reading per-user config files from
~/.config or similar?

I don’t know what the Python API looks like.  The gettext manual
mentions an API with the ‘gettext.’ prefix, dunno if that’s a different
thing.

Yes.

It’s interesting that we find it surprising.  ;-)

Perhaps rename the phase to ‘disable-i18n’ for now, because that’s
really what it does AIUI.

OK to push with these changes!
