Thanks, but this is wrong: it should offer completion only on Info
buffers that already exist in the current session.  Completion on
manuals installed on the system is perhaps for "C-u C-h i" or some
variation of it.

The purpose of this command is to assist with switching between
manuals that are already loaded, not in adding others.
