Enhance manpage with use of emphasis instead of strong quote

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.
