[PATCH 1/2] checkout: add tests for -b and --track

From
René Scharfe <l.s.r@web.de>
Date

Message-ID
<ebe696b2-bf68-ccd1-b930-dce274ec9279@web.de>
In-Reply-To
<20200523162914.GA2178752@coredump.intra.peff.net>

Test git checkout -b with and without --track and demonstrate unexpected error messages when it's given an extra (i.e. unsupported) path argument. In both cases it reports:

   $ git checkout -b foo origin/master bar
   fatal: 'bar' is not a commit and a branch 'foo' cannot be created from it

The problem is that the start point we gave for the new branch is "origin/master" and "bar" is just some extra argument -- it could even be a valid commit, which would make the message even more confusing. We have more fitting error messages in git commit, but get confused; use the text of the rights ones in the tests.
