Subject: SSID printing: escape space at beginning end, backslash
X-Git-Tag: v3.2~6
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=3f61273315002a8f2ca7f63f9eec0b3497905e03;p=thirdparty%2Fiw.git

SSID printing: escape space at beginning end, backslash

To make SSID printing point out spaces at the beginning
and end explicitly escape them with \x20. Also escape
the backslash itself so that it's unambiguous.
