As part of the work to make the frontend more language agnostic, this was dropped - it now sends the current cell and the cursor position to the kernel and expects that to work out what it should provide information about.

Indeed,and having a space after the comma, or not was returning different results.

You can also select and shift-tab, it should give info only on selection.

It was not technically "smart", and we don't use the new message spec at all, 
so I doubt this will be a simple "fix".
