company-irony will break company-yasnippet.

After add company-irony to company-backends, company-yasnippet not work. For example, for| will show yasnippet's candidates but after added company-irony to company-backends, for| only show "forward_iterator_tag".

buffer variable: company-backends Value: ((company-irony-c-headers company-irony) company-gtags company-yasnippet (company-capf :with company-dabbrev-code company-files))

[Sarcasm]

if you want company-yasnippet you have to add it to the group of company-irony:

(company-irony-c-headers company-irony) ...

should become:

 (company-irony-c-headers company-irony company-yasnippet) ...

Thanks, it works.
