Hi Bert, > Subject: format-patch: document and exercise that -o does only create the trailing directory s/does only create/only creates/ ? Anyway, as a prepatory patch, I don't think that it's necessary. Maybe it's just me but I assume that most tools create at most one directory deep. Even mkdir won't created nested dirs unless you pass `-p`. I dunno.

The second is that when we write tests, we shouldn't put Git commands in the upstream of a pipe because if they fail, their return codes will be lost and we won't be able to fail the test properly. > +' > + > +test_expect_success 'format-patch -o with leading existing directories' ' > + git format-patch -o patches/side master..side && > + test $(git rev-list master..side | wc -l) -eq $(ls patches/side | wc -l) > +' > + > +test_expect_failure 'format-patch -o with leading non-existing directories' ' > + rm -fr patches && > + git format-patch -o patches/side master..side > +' As above, I wouldn't really call this a bug in Git.
