Hi folks,

I'm not sure whether this is just me, but when I run "read" in a fish
non-interactive script, I lose the capability to use backspace and
arrow keys. You can simulate this bug with "fish -c read". I'd guess
that this bug is caused by the read function relying on the
capabilities of an interactive terminal, and when it's not run under a
non-interactive terminal, it falls back to STDIN.

This isn't a huge deal, as I can use Bash for the shell script (since
"bash -c read" does work). Fish is nicer to program in, though :)
