Yes and no. However eventually the two works the same way,
"(errmsg(gettext_noop("hogehoge"))" is a shorthand of
1: char *msg = gettext_noop("hogehoge");
...
2: .. (errmsg(msg));
That is, the line 1 only registers a message id "hogehoge" and doesn't
translate. The line 2 tries to translate the content of msg and it
finds the translation for the message id "hogehoge".

Ah, right. we get a complain if no value parameters added. We can
silence it by adding a dummy parameter to errmsg, but I'm not sure
which is preferable.
