Subject: cfgfile: handle missing command line option values
X-Git-Url: https://git.unchartedbackwaters.co.uk/w/?a=commitdiff_plain;h=7763cc77a7fe11dd71983e072b295cad69884e0e;p=francis%2Fwinuae.git

cfgfile: handle missing command line option values

parse_cmdline_option() keeps unknown command line options in the
all_lines list. A trailing option such as -G reaches this path without
a value, which passed NULL to my_strdup() and crashed before the GUI
could start.

Store an empty string when no value is present so argument-less
options can still be represented in the saved option list.
