  agreed that it's a good read and should be referenced more often.
one thing i don't see there, and it's based on an observation someone
once made (i believe on this list), is that even if there is
absolutely no ambiguity in a command, even if there are no pathspec
arguments, it's still worthwhile to add a trailing "--":

  $ git command options/treeish ... --

since that guarantees that git will waste no time trying to identify
any ambiguity since you're being so precise. is that worth mentioning
in that page?
