This won't work with older versions of the Almquist shell (without
prepending `testid' and `git_p4_test_start' with a `$', that is):

  $ ash-0.5.2 -c 'a=4; b=2; echo $(( 1 + (a - b) ))'
  ash-0.5.2: arith: syntax error: " 1 + (a - b) "

Still, it works with all the other POSIX-ish shells that I've tried,
including dash 0.5.5.1 on GNU/Linux, NetBSD 5.1 /bin/sh and /bin/ksh,
and Solaris 10 /bin/ksh and /usr/xpg4/bin/sh, so it might not be worth
worrying about.

Same goes for other similar usages in the rest of the patch, such as
"git config git-p4.detectCopies $((level + 2))"
