Greg, unfortunately, you cannot rewrite it like that. You have to put
quotes around (cat $tmp), or each token will end up on its own line in the
command buffer. (And in fish, you cannot do command substitution inside
quotes.)
Something like
[...]
commandline -r ""
cat $tmp | while read -l cmd; commandline -a "$cmd" ""; end
[...]
would even handle multiple lines as expected.
