xphung on github said: "config2help currently doesn't work on OS X, it

terminates parsing of Config.in at first blank line. This is because
getdelim() in portability.c returns -1 whenever the line comprises only
a single linefeed character. Fixing this was a trivial change to two lines
(see below), and config2help now works on OS X but I haven't regression
tested this on any other commands which rely on getdelim()"
