bug#35533: 26.2; Weird <i> and <I> keybindings in an (insert-table) environment.

[Vladimir Nikishkin]

The bug (or, rather a strange behaviour), can be reproduced in the
following way:
1)Create a new buffer.
2)Insert a text table by calling M-x insert-table RET
3)Put the point in the first cell.
4)Type: C-h w table-forward-cell RET

You will see a keybinding called 'C-c C-c <i>'.
You can see similar weird keybindings for other table-* commands.

Those actual keys are nowhere to be found, and no-one on the
#emacs channel on Freenode knows what they are.

It would be nice to either document those keys. Or, perhaps,
it's a bug in Emacs.

This behaviour has been reproduced by friendly people on
#emacs with different setups.
