Jeff King aadbe44f88 grep portability fix: don't use "-e" or "-q"
System V versions of grep (such as Solaris /usr/bin/grep)
don't understand either of these options. git's usage of
"grep -e pattern" fell into one of two categories:

 1. equivalent to "grep pattern". -e is only useful here if
    the pattern begins with a "-", but all of the patterns
    are hardcoded and do not begin with a dash.

 2. stripping comments and blank lines with

      grep -v -e "^$" -e "^#"

    We can fortunately do this in the affirmative as

      grep '^[^#]'

Uses of "-q" can be replaced with redirection to /dev/null.
In many tests, however, "grep -q" is used as "if this string
is in the expected output, we are OK". In this case, it is
fine to just remove the "-q" entirely; it simply makes the
"verbose" mode of the test slightly more verbose.
