[PATCH] BUG/MINOR: cfgparse: Support configurations without newline at EOF

[Tim Duesterhus]

Fix parsing of configurations if the configuration file does not end with
an LF.

This patch fixes GitHub issue #704. It's a regression in
9e1758efbd68c8b1d27e17e2abe4444e110f3ebe which is 2.2 specific. No backport
needed.
