"git blame" -> "'git blame'", perhaps. It is an interesting observation. I thought "git blame" was quite bad at streaming (i.e., until it learned the origin of each and every line, it never produced any output the user asked for), which actually would make it a non issue that the output the user wanted gets mixed with the progress messages and other garbage. Unless the user understands that "git blame" is not spending time itself, but is waiting for necessary blobs to be fetched from the promisor, and is expected to wait unusally longer than the fully local case, having to stare at a blank/unchanging screen would make it uneasy for the end-user and that is why we have progress eye-candy. I am OK for promisor.quiet being optional, but I am torn when I imagine what comes next. On one hand, I myself probably would find it neat to make these lazy fetches happen completely silently as if nothing strange is happening from the point of view of end-users (except for some operations may be unusually slow compared to fully local repository). On the other hand, I suspect people will be tempted to push it to be on by default at which time it may hurt unsuspecting (new) users who may have been helped by progress bars. > diff --git a/Documentation/config/promisor.txt b/Documentation/config/promisor.txt > new file mode 100644 > index 0000000000..98c5cb2ec2 > --- /dev/null > +++ b/Documentation/config/promisor.txt > @@ -0,0 +1,3 @@ > +promisor.quiet:: > + If set to "true" assume `--quiet` when fetching additional > + objects for a partial clone.

Of course you'd later have to say ... git -C repo cat-file -p $blobhash instead of "$(cat blobhash)". Even simpler, I wonder if you can remove this hash-object invocation, and then do ... git -C repo cat-file -p :foo.t > + rm -rf repo/.git/objects/* && This! IS!

I'd prefer not to see manual destruction of $GIT_DIR/objects/* or manual futzing of repository format version and extensions. These configuration variables are *NOT* for end-users to futz with, and the tests should not be doing so either.
