Re: [PATCH 2/3] test: improve rebase -q test

With such a helper function this could be reduced to a single line:

  test_string_equal "(master)" "$(__git_ps1)"

without loss of functionality or debuggability, because in case of a
failure it would output something like this (bikesheddable, of
course):

  Error:
    expected: "(master)"
    got: "((deadbeef...))"

Yeah, that looks sensible.
