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.
