Subject: tests/util/grub-shell: Allow specifying non-default trim line contents
X-Git-Tag: grub-2.12-rc1~157
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8e8e44399718d4298de522a45d5de41855d8bcc1;p=thirdparty%2Fgrub.git

tests/util/grub-shell: Allow specifying non-default trim line contents

This will be useful for tests that have unwanted output from setup. This is
not documented because its only intended to be internal at the moment. Also,
--no-trim is allowed to explicitly turn off trim.
