#190350: vi mode glitch

Whenever you do some non-inserting edit command, like 'x' or 'd',
that becomes the command-to-repeat and no further insertions may be repeated.

1. Start a new bash shell
2. 'set -o vi'
2. Type 'kekepop<esc>hxi\<esc>.'
3. You end up with 'kekepp' instead of 'kekep\\p'.

This patch fixes it and tries to fix redoing the 'I' command as well.
I'm not sure about 'c', though.
