Subject: fix bsd shell negation
X-Git-Tag: v1.5.6-rc0~64
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=bbf08124e0a87658a76b53a05d67227fa3b4e7b9;p=git.git

fix bsd shell negation

On some shells (notably /bin/sh on FreeBSD 6.1), the
construct

  foo && ! bar | baz

is true if

  foo && baz

whereas for most other shells (such as bash) is true if

  foo && ! baz

We can work around this by specifying

  foo && ! (bar | baz)

which works everywhere.
