Revert applying shell quoting to commands for ``echo_with_pager``
and ``edit``. This was intended to allows spaces in commands, but
caused issues if the string was actually a command and arguments, or
on Windows. Instead, the string must be quoted manually as it should
appear on the command line. :issue:`1514`
