+dnl taken from Autoconf's m4sh.m4, GPLv3+

<p>I'm not totally sure about this part: it might not be needed, and if it is I'm not sure <code>AS_LITERAL_WORD_IF</code> would be available.  This code is what Autoconf has nowadays, but the inspiration I got from cryptsetup has <code>AS_LITERAL_IF</code> instead (but it seems to be buggy in some cases if I trust the documentation).<br>
Anyway, we can fix this if a problem arises</p>
