Subject: ldlinux: Don't return NULL on KEY_ESC.
X-Git-Tag: syslinux-5.00-pre11~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b8dfe78a33e70f657f8aadb48de644a92bf82850;p=platform%2Fupstream%2Fsyslinux.git

ldlinux: Don't return NULL on KEY_ESC.

The old command line code in 4.06 ignores KEY_ESC and KEY_CTRL('C') so
we should do the same. What currently happens if a user hits ESC is
that we return from edit_cmdline() as though we'd timed out waiting
for user input.
