Undefined index options_form()

If you can't reproduce that this is impossible to fix, maybe some custom code problem.
Additional this doesn't seem to be a major problem, so let's mark as fixed.

One place this happens is when a module registers a plugin via hook_views_plugins() but does not provide the 'help topic' key in the plugin data. This is checked for some plugins, but not for access_options, cache_options, exposed_form_options, and pager_options plugins. Attached is a test-less patch, which can serve as a starting point for getting this fixed.

FWIW, I first observed this with the views_content_cache module.

This might not be the preferred method (perhaps we are to assume the plugin will provide all the correct data) but this patch works for me and fixes the error when the help topic is missing. So... marking RTBC but I understand this this might not be committed. Thanks!

I agree its fine to not require those modules to implement help.

Committed and pushed to 7.x-3.x thank you
