Command names in index of Texinfo manual

[Gavin Smith]

A few times I have struggled to find the documentation of some Texinfo
commands (like @w, or @c) because there isn't an index entry which is
the command name exactly. (Pressing ic<ret> in the info browser takes
you to the node "Printing Indices and Menus".) I think it would be
best to have an index entry for each Texinfo command which is the
command name exactly to ease finding the right place. Has there been
any thought about this before?
