Trailing whitespace in above line :)

Hmm, this works with "-drtinherit=1" and "-drtinherit,<other opts>" but
fails to detect the "-d rtinherit" case, because the regexp expects some
character after "rtinherit". I think this change could fix it:
- egrep -q "rtinherit([^=]|=1)" && \
+ egrep -q "rtinherit([^=]|=1|$)" && \
If this looks ok to you, I can fix it on commit (along with the
whitespace issue).
Thanks,
