If you accidentally type 'u' in vim, you can "redo" it by ^R. There is
also the "set compatible" option, but it isn't exactly "compatible" with
the nvi behavior.
In nvi, typing 'u' can undo the last operation. Then repeating the undo
command with '.' keeps undoing changes until the buffer is reverted to
its original state.
In vim, with "set compatible" enabled", typing 'u' repeatedly toggles
between the last two states of the buffer. In "compatible" mode I am
not sure of how to undo multiple changes. In "set nocompatible" mode,
typing 'u' repeatedly undoes multiple changes, and typing '^R' multiple
times redoes them.
