Subject: [PATCH] doc/Makefile: avoid spurious whitespace in environment
 variables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* doc/Makefile (%.pdf): Ensure that LANG and LC_ALL are set to "C",
  not "C   " (with trailing whitespace).

Make evaluation order produces spurious whitespace in variables when a
variable definition is followed by whitespace plus a comment.
