-Protect against a fax VL(n) codeword commanding a move left. Without
-this, a malicious input file can generate an indefinitely large series
-of runs without a0 ever reaching the right margin, thus overrunning
-our buffer of run lengths. Per CVE-2011-0192. This is a modified
-version of a patch proposed by Drew Yao of Apple Product Security.
-It adds an unexpected() report, and disallows the equality case except
-for the first run of a line, since emitting a run without increasing a0
-still allows buffer overrun. (We have to allow it for the first run to
-cover the case of encoding a zero-length run at start of line using VL.)
