[PATCH 0/2] Advice upon clone --recurse-submodules --reference

This patch set came about because of a situation in $DAY_JOB described in the commit message of patch 2. I found the existing documentation and error messages unclear, so I have improved them.

Jonathan Tan (2):
  Doc: explain submodule.alternateErrorStrategy
  submodule--helper: advise on fatal alternate error
