With a spaced --path, the parallel workers get the path split into words
and reject the stray words as unknown options (the bug #755 fixes). Unknown
options used to exit 0, so every worker "succeeded" having installed
nothing, and this case's exit-code assert passed while the count assert
next to it was already an xfail for #755.
Now that unknown options exit 1, the parent exits non-zero there, which is
the truth. The exit-code assert becomes an xfail for #755 like its
neighbour; both will report "appears to have landed" once #755 merges.
