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.
