- caution about wild repos needing to be manually created on the
receiving side (because nothing gets auto-created now)
- caution about the right and wrong way to "delete" a config variable
- a few other minor fixes
to my eternal shame (considering how proud I am of my documentation)
this was not mentioned anywhere! I'm getting old...
thanks to Pierre Habouzit for catching this
(also slipped in a few other minor doc changes. I wouldn't mix
unrelated stuff in a commit when doing code changes but it seems ok to
do this for docfixes, for some reason).
