Weird repeat-undo issue

[MavEtJu]

I'm experiencing a strange issue, not reproducible on demand but when it happens you can reproduce it over and over:

Use "i" to insert some text. Go to a random next line, press "." to repeat it. Now pressing "u" I would expect it to undo the inserting via ".".

However, pressing "u" removes the last two letters of the insert. Pressing "u" again inserts the second last letter again. Pressing "u" again removes finally the whole initially inserted text.

So "i" to insert "self.". Placed cursor on "foo". Pressed "." created "self.foo". Pressed "u" created "selfoo". Pressed "u" created "selffoo". Pressed "u" created "foo".

It happens after a couple (undetermined number) of "."'s on random lines.

Good luck on this one.....

Today's version works fine, and the weird "Weird repeat-undo issue" is resolved!
