It has been launched with the following command-line arguments:
arg[0] = "emacs"
arg[1] = "--eval"
arg[2] = "\"(setq-default"
arg[3] = "default-major-mode"
arg[4] = "'sh-mode)\""
arg[5] = "/tmp/bash-fc-247955888988243"
The shell that launched $FCEDIT as an editor, looked at its value, saw
that it had space characters in it, and split the $FCEDIT value to
several separate arguments at every unquoted space.
Try firing up Emacs with the following two commands, and look at the
*Messages* buffer to spot the difference:
emacs -nw "foo" "bar"
emacs -nw "foo bar"
The first should display:
("emacs" "-nw" "foo" "bar")
but the second should display:
("emacs" "-nw" "foo bar")
It may be possible to quote FCEDIT's value in some complex manner to
achieve the effect of second list, where the s-exp passed to --eval is a
single entry in the command-line argument list. Is it worth all the
trouble to get it `right'? My own personal preference at this point is
to say `No, not really. I can write a shell wrapper, and be done with
it in half a minute or so' :-)
