The revents should only contain the bit flag for the event you asked for, and
EV_ERROR, at least from libevs side (you can feed other events manually, or
combine masks).
Now, regardless of receiving an error, you can always stop a watcher that
has been initialised, whether libev knows about it or not, so calling stop
functions is safe.
In addition, EV_ERROR usually means a programming error, so you never need
to check for it in a correctly wirtten program :) You can just assume that
a timer will always get an EV_TIMEOUT revents.

For some reason, that russian site is very popular, but has a completely
outdated libev library and documentation. However, the antique libev
version on that side at least should match the documentation.
The documentation, incidentally, links to the most up-to-date version of
the docs in the DESCRIPTION:
