Subject: [PATCH] sym-gtest: Don't include empty words.
Organization: Straylight/Edgeware

From: Mark Wooding <mdw@distorted.org.uk>

An empty word in a command like `set LABEL' provokes a segfault from
sym-test -- not entirely unreasonably considering that sym-test is a
quick lash-up and not intended to be robust against bogus test scripts.
So filter them out in advance.
