Thanks...  but here I am nitpicking again, sorry :)

The previous test case creates the 'patches' directory and leaves it
behind, and this test implicitly relies on that directory to check
that 'format-patch -o' can deal with already existing directories.  So
if the previous test case were to fail early or were not run at all
(e.g. './t4014-format-patch.sh -r 1,137'), then that directory
wouldn't exist, and, consequently, this test case would not check what
it was supposed to.

I think it would be better to be more explicit and self-contained
about it, and create a leading directory in this test case:

   mkdir existing-dir &&
   git format-patch -o existing-dir/side master..size &&
   ls existing-dir/side >list &&
