Sometimes the user makes an explicit request, though. So it's "idle mode 
vs manual mode", not "Company vs complete-symbol".

Still, the fact that user called `M-x company-complete' inside a comment 
doesn't tell me that they actually want to see completions from 
`company-capf' and not some other backend like `company-dabbrev'.

Likewise, user pressing C-M-i inside a comment might prefer not to talk 
`lisp-completion-at-point', but some other completion function that goes 
after it that's more suited for completion in comments.

If we really want to use `lisp-completion-at-point' in comments in more 
cases, I'd try to detect whether we're probably in a code sample (by the 
extra indentation, maybe), and otherwise return nil.
