[PATCH v2 00/12] Improve git-pull test coverage

This patch series improves test coverage of git-pull.sh.

This is part of my GSoC project to rewrite git-pull into a builtin. Improving
test coverage helps to prevent regressions that could occur due to the rewrite.

The previous patch series can be found at [1]. Note that it is now based on
jc/merge in pu.

Besides fixing issues raised in the last round, some failing tests have been
added to demonstrate some bugs in git-pull.sh, and some tests are modified to
reduce their dependence on git-pull's functionality so that irrelevant test
suites will not break during the rewrite.
