Is this new?  That part of the Makefile hasn't changed in the last two 
months, after it was introduced.

Again I tested this with (GNU) sed with --posix, and it gave the expected 
result.  The reason I chose the former expression instead of the latter is 
because it's how I usually write such patterns.  After reading the POSIX 
standard, it turns out that a semicolon is required after the 'q'.  Fixed 
(a3b654e069) and closing.
