Subject: (check-programs-vs-x):
X-Git-Tag: v5.1.0~223
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9bc557bf8812a05ccd22343ffb7c9ce09d010ca9;p=thirdparty%2Fcoreutils.git

(check-programs-vs-x):
Work even if $(programs) contains '$'.
Work even if 'missing=1' in environment.
Don't report an error simply because $(programs) outputs nothing.
