An easy work-around for that is to use an old vi trick: when you want to do
the following:
alias filter='sed 's/foo/bar/g''
just press <CTRL> + V before any of the inner quotes, and that will tell the
shell to keep the quotes as literal part of the string. This will work with
escape sequences, newlines, etc. Try it on the command line, you'll see what
I mean.
