Subject: 26.2; Weird <i> and <I> keybindings in an (insert-table) environment.
Date: Thu, 02 May 2019 19:27:15 +0800

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.

Just for clarity, the second step is to type: M-x table-insert RET
Then, of course, hit RET to accept all of the defaults.

I believe it's a bug.
'C-h v table-cell-map RET' shows at the end that the bindings are to
'j', 'm', 'I' and 'i', and not to their printed representations.

I attach a patch that adds a missing '?' to all those characters, in
table-cell-bindings.

Best regards,
Mauro.

I think it's generally allowed to use the symbol instead of characters
(it's an XEmacs thing).  But some other code in table.el didn't account
for that (so in combination it's a bug).

I adjusted the commit message a bit, and pushed to master.
