to demo "git fetch" as part of intro class, i decided to throw in an
example of adding a remote and doing "git fetch --dry-run", for which
the man page insists:
--dry-run
Show what would be done, without making any changes.
except it clearly *does* do something, in the sense of apparently
downloading all that content. certainly, i could see all the object
compression and downloading, and the object store was noticeably
larger after that command ran; predictably, though, none of the
branches of the remote i added were visible (yet).
i ran the dry run fetch again, and it finished almost immediately,
so clearly even a "dry run" fetch really does all that fetching; it
just doesn't add that content to (i'm guessing) .git/refs/.
after i do a proper "git fetch" on that remote, unsurprisingly, i
see all the branches from the remote. so why is it referred to as a
"dry run" when stuff is actually being fetched? that seems just a tad
misleading.
