If you're doing command substitution in a context where you have
to suppress word-splitting yourself, then you're choosing between

    outer_cmd foo "`inner_cmd bar`" baz

and

    outer_cmd foo "$(inner_cmd bar)" baz

Many (including me) would consider "`...`" less legible.

The backslash isn't necessary if the vertical bar is at the end of
the line.
