Snippet expansion only occurs for overloaded functions.

[toojays]

emacs-clang-complete-async f01488 auto-complete 1.4ish (a4f83db) yasnippet 0.8beta (20130218.2229 from MELPA)

When expanding a non-overloaded function, snippet expansion does not occur.

For example:

#include <stdio.h>

void main (void)
{
  fclos
}

with the cursor after "fclos", the completion fclose(FILE __stream) will be offered. But when pressing RET to expand, point is moved after fclose(FILE __stream), and snippet expansion does not occur.

This patch seems to fix it:

I haven't seen this problem on my site (with a few tries on the latest code), maybe I need to switch to a cutting edge version of auto-complete to reproduce this problem.

Hmm, I can no longer reproduce this either, even when rolling back to the revision of emacs-clang-complete-async I mentioned when I opened the issue.

This problem must have been due to some misconfiguration on my part, which I accidentally fixed while developing this patch.

Apologies for the noise. :(
