counsel-describe-function and `...' quoted stuff

I use counsel-describe-function and counsel-describe-variable as drop-in replacements for the standard commands. However, there's one thing where the standard ones work better.

When point is somewhere in ``some-command-name'and you doC-h f`, then `some-command-name` is used as default value. With the counsel variants, the quoting with ` and ' prevents that (actually, it's the trailing single quote which is the problem).
