The Debian package checker "lintian" was making noise about
wpa_supplicant.conf(5). It was caused by a line beginning with ', which is
apparently not liked by man(1).
I suggest the use of <emphasis>word</emphasis> where 'word' is used at the
moment.

These are expected in most cases and there is no need to confuse users
with the messages in stderr (perror was used here). These are now only
shown in debug output and EOPNOTSUPP errors are silently ignored.
