doc/Makefile: Don't show Makefile comments in output

The comments makes sense when editing Makefile, but not when watching its
output where it looks too much like error messages.

#!/bin/sh

"$TESTDIR/hghave" symlink || exit 80

hg init a
ln -s a link
cd a
echo foo > foo
hg status
hg status ../link
