Re: bind -x and multiple prompt/command lines

Here are simplified versions of two functions that I have written. Both are
inspired by similar functions floating around on the zsh mailing lists. The
first copies the previous word on the command line, and the second one
converts three consecutive dots (...) into ../.., and you can then keep
adding levels by typing . repeatedly.

Note that I am by no means an expert in Bash programming, so I'm sure the
same thing could be done more elegantly.

bind -x '".":_rationalise-dot'
bind -x '"\e:":_copy-previous-word'

_copy-previous-word () {
    local -a words
    eval words=($READLINE_LINE)
    #NOTE: copies quoted words correctly, but does not insert with the
escape intact

_rationalise-dot () {
    if [[ ${READLINE_LINE:0:$READLINE_POINT} == *\.\. ]]; then
