Add short-circuit boilerplate to plugins
Set a g:loaded_* flag to prevent repeated reloads, and refuse to load at all if &compatible is set or if required features are missing. Some more accommodating plugins avoid the problems 'compatible' causes by saving its value at startup into a script variable, setting the option to the Vim default, and then restoring it when the plugin is done, to prevent any of its flags from interfering in the plugin code: let s:save_cpo = &cpo set cpo&vim ... let &cpo = s:save_cpo unlet s:save_cpo I don't want this boilerplate, so I'm going to do what Tim Pope's modules seem to, and just have the plugin refuse to do a single thing if 'compatible' is set.
