Subject: ccanlint: protect against the function element in the doc section being null
X-Git-Url: http://git.ozlabs.org/?p=ccan;a=commitdiff_plain;h=020983311c9f58bee8d528f80c7c097c4405975c

ccanlint: protect against the function element in the doc section being null

This can happen if the documentation doesn't have a properly formatted summary line,
and it causes the examples_relevant test to segfault.
