Thinking on this more, I wonder if we should just do something like
this:

diff --git a/t/lib-httpd.sh b/t/lib-httpd.sh
index bfdff2a..c82b4ee 100644
--- a/t/lib-httpd.sh
+++ b/t/lib-httpd.sh
@@ -64,7 +64,9 @@ case $(uname) in
 esac
 
 LIB_HTTPD_PATH=${LIB_HTTPD_PATH-"$DEFAULT_HTTPD_PATH"}
-LIB_HTTPD_PORT=${LIB_HTTPD_PORT-'8111'}
+if test -z "$LIB_HTTPD_PORT"; then
+	LIB_HTTPD_PORT=${this_test#t}
+fi
 
 TEST_PATH="$TEST_DIRECTORY"/lib-httpd
 HTTPD_ROOT_PATH="$PWD"/httpd

and drop the manual LIB_HTTPD_PORT setting in each of the test scripts.
That would prevent this type of error in the future, and people can
still override if they want to.

Any test scripts that are not numbered would need to set it, but we
should not have any of those (and if we did, the failure mode would be
OK, as Apache would barf on the bogus port number).
