Subject: Removing unnecessary ()'s doesn't seem to make any time difference on
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1922d8eb8d715727406171cbcceb11cad4c2afbc;p=binutils-gdb.git

Removing unnecessary ()'s doesn't seem to make any time difference on
cygint.  I think modern shell's execute this internally without a call
to a separate shell process.  I've left the change in anyway.  It may
help on older, slower machines.
