Whatever is that value, the number of resulting undo steps can sometimes be much smaller. Thanks Charles.

Undo not really unlimited

^R does not work always now, and it is because of the I-find mode. Terminal becomes garbled. Press ^R to refresh the terminal. Terminal is refreshed, I-find is still there because no key has been pressed in the meantime. Terminal becomes garbled again. Press ^R to refresh the terminal. Nothing happens, terminal still garbled.

I cannot close this bug, please do it for me.

^R has two functions now, it seems. Possibly the terminal wa trashed continuously so I had an impression that only I-find appears.

^R does not refresh the terminal anymore, instead "I-find"
