[PATCH v3 0/3] repo-settings: fix checking for fetch.negotiationAlgorithm=default

This regression is not new in v2.35; it first appeared in v2.34. So, not urgent.

Changes since v2:

 * Also fix the fact that fetch.negotationAlgorithm=$BOGUS_VALUE no longer
   errors out (yet another regression, this one dating back to v2.24.0), and
   add a test to make sure we don't regress it again.
 * Add 'consecutive' as a synonym for 'default', and remove 'default' from
   the documentation to guide people towards using 'consecutive' when they
   want the classic behavior.

Changes since v1:

 * Put the common code in two testcases into a function, and then just
   invoked it from each
