Expected behavior
2-1 chord must always escape its argument, so that the shell doesn't
mangle it.
Unexpected behavior
It fails to escape the argument.
I haven't yet succeeded at breaking 2-1 chord with rc shell. But it's
easy to break it with acmeshell=/bin/sh.
Steps to reproduce the problem
Run Acme with acmeshell=/bin/sh. Run 2-1 chord on <echo with '$HOME'
as its argument. '$HOME'\n must be printed. Instead, it prints the
actual value of home directory.
