Some day we might want to introduce a gettext_ln function or something
similar.  But that doesn't seem urgent; I wouldn't be appalled by
having to read 'gettext "foobar" && echo' in a block surrounded by
braces (or even a subshell, even though it makes shells waste a
fork()).

As for what to call the envvars, I have no strong preference there,
either.  If you don't care about compatibility with the real gettext.sh
then it should be possible to do the variable munging automatically,
using a loop:

	for var in $(git sh-i18n--envsubst --variables "$fmt")
	do
		eval "sh_i18n_$var"=\$var
		export "sh_i18n_$var"
	done

with an understanding that git sh-i18n--envsubst substitutes in
${sh_i18n_$var} where it sees '$var' in the format string.

But if we do want to use the real envsubst some day then that is not
possible.  I dunno.
