[PATCH v2 0/2] tests: some touchups related to the --stress feature

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

then the current options are very confusing.

This is my attempt at making them less confusing.

Changes since v1:

 * Now the patches actually adjust the documentation according to the
   changes ;-)

Johannes Schindelin (2):
  tests: let --stress-limit=<N> imply --stress
  tests: introduce --stress-jobs=<N>
