The use of parens is not needed, and adds an additional invocation of
/bin/sh for each paren pair (which is significant on cygwin). The one
time when they are needed is if you also want to squelch messages from
/bin/sh itself (i.e. "command not found"), in which case you'd need
the redirection to be outside of the parens anyway.
