Subject: readconfig: Don't display "(null)" labels when hitting TAB
X-Git-Tag: syslinux-5.10-pre2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=557ad5544fbaa893936d31e44038c3570030a798;p=platform%2Fupstream%2Fsyslinux.git

readconfig: Don't display "(null)" labels when hitting TAB

It is entirely legitimate for a menu entry to have a NULL label or
displayname. Since these entries are not used for execution, skip
displaying them in print_labels() when hitting the TAB key.
