org-store-link and help for a key

[Maxim Nikulin <manikulin@gmail.com>]

Either I missed something obvious or org-store-link from a help page for 
a keystroke works incorrectly

Let's try to save a link to the *keystroke* help for e.g. org-insert-link:

1. Open help page with =C-h k C-c C-l=
2. Switch to the help buffer =C-x o=
3. Store link =M-x org-store-link RET=
4. Switch back to the org file =C-x o=
5. Insert link =C-c C-l RET RET=

I get =[[help:C-c]]= and an error if I try to follow the link with =C-c C-o=

     user-error: Unknown function or variable: C-c

If I ask a help page for the *function*

1b, =C-h f org-insert-link RET=

I get the working link =[[help:org-inser-link]]=. I expect the similar 
result for the keystroke help link or maybe something special that leads 
to the description of the current keystroke binding.

Such behavior exists for ages, at least since 8.2.10 till current master.
