Subject: Fix string options with empty default
X-Git-Tag: v4.0~39
X-Git-Url: http://winboard.nl/cgi-bin?p=uci2wb.git;a=commitdiff_plain;h=142b07fac63966ef4e12a5ae0d1d7875905a8764;hp=c33a1432ec909fcba0049c492cebbcbda21886c6

Fix string options with empty default

When sscanf finds nothing after 'default', it does not touch the target
array at all, rather than putting an empty string in it. So the target
is now initialized to an empty string before the sscanf.
