[I know, some serious thread necromancy going on here...]

I too am interested in the rationale for bash's C-x C-e command invoking:
  fc -e "${VISUAL:-${EDITOR:-emacs}}"

fc itself has its own ordered list for editors, which is different fromm C-x C-e.
If nothing else, this is a mite confusing. (From "help fc": "Default is FCEDIT, 
then EDITOR, then vi").

How would you feel about either of the following:

A) a patch to remove the "-e" special casing, relying on "fc" to do its job

or

B) a patch that changed the C-x C-e ordered list to:
  $FCEDIT;$VISUAL;$EDITOR;emacs?

It goes without saying that the offer of updated documentation goes with these :)
