In git 1.7.0.4, what's the correct way to preview what a "git pull"
would do, without actually doing it? Unlike most git subcommands,
pull seems not to understand --dry-run:
$ git pull --dry-run
sed: can't read {pathname suppressed}/.git/FETCH_HEAD: No such file or directory
You asked to pull from the remote '--dry-run', but did not specify
a branch. Because this is not the default configured remote
for your current branch, you must specify a branch on the command line.
Trying the "fetch" part of pull by itself, at least fetch doesn't
mistake --dry-run for a remote name, but it doesn't seem to
implement it either -- instead of a report of what it would do,
there's no output at all:
$ git fetch --dry-run
$
I'm guessing that I may need to actually do the fetch in order
for git to know what the remote has, but then how would I find
out exactly what merge command "pull" would have issued (so as
to try adding --dry-run to it)?
