[The argument there is that if `C-x u u u...' repeats `undo' then typing
`u' directly after that will not insert a `u' character.]
Fair enough. And thank you - it's always good to see real arguments for
and against a proposal.
It's a good argument. Not a particularly strong one, IMO, but reasonable.
It's not strong because there are other, simple ways of exiting `undo' so
`u' will then insert (`<left> <right>', `x DEL', whatever).
This is similar to arguments against binding keys in `isearch-mode-map'
to do things in Isearch because it stops them from ending Isearch.
Yes, some people might want to use `C-x u' for `undo' AND want `C-x u u'
to insert `u'. My vote would still be for making `C-x u u' repeatable.
You can't please everyone, unless you add an option or you have two
different commands (or you abuse some prefix-arg combination, and that's
already pretty overloaded).
To accommodate that argument, I would also vote for binding `C-x u' to a
new command, `undo-repeat', as mentioned earlier. (Or perhaps just reuse
the previously used name for `C-x u': `advertised-undo'.)
Anyone wanting to have `u' to insert directly after `C-x u' could easily
opt out in that case, by changing the key binding to the original,
non-repeatable `undo'.
Or if you want to be conservative here, make binding `C-x u' to
`undo-repeat'/`advertised-undo' opt-in instead of opt-out. I'd vote for
that too.
Bottom line: we should provide a repeatable undo command for `C-x u',
whether bound by default (preferable) or not (ok).
