Another alternative that came to me this morning, that even means we
don't really need to rename the option, only re-document it. What if
SyncFirst simply moved packages to the top of the targets list by
default? Since right now we simply keep targets in alphabetical order
(outside of necessary dependency reordering), what if being in
SyncFirst gave you a free ticket to the head of the line?

If one kept pacman in SyncFirst, it would get pulled up, and then via
dep reordering, would be behind only the packages it depends on, which
is kind of what we have wanted all along, except now we continue to
install everything else as well. If someone was silly enough to
interrupt the sync operation, there is a slightly smaller chance they
leave themselves in a bad situation.
