This patch series fixes bugs in git and git's testsuite to allow all tests
to pass when the working directory contains whitespace and/or shell
metacharacters.

The first three patches in this series fix bugs in git itself that were
uncovered in the process of fixing the test suite. Each contains additional
tests and/or updates to existing tests to exercise the bug in question.

Patches 4 and 5 set up an abstraction for safe handling of editor variables
in tests when we have odd paths, and 6-8 fix bugs in the test suite itself.
Patch 9 cleans up some instances of the unportable export FOO=bar construct
in the test suite; and 10 arranges for the test suite to always run with the
trash directory name containing various metacharacters, to help prevent
regressions in the future.

Signifigant changes since v1:
  * Rebase against master
  * Drop some unnecessary quotation additions
  * Use "$@" not $@ in editor invocations in the fix to git-send-email, to
    match builtin-tag.c
  * Be more verbose in the config.c and git-send-email.perl patch commit
    messages
  * Rename 't/trash' to 't/trash directory' to try to trip up more bugs in
    the future
  * Add a patch to convert all export FOO=bar to FOO=bar; export FOO in t/*.sh
  * Noted why t/t7505-prepare-commit-msg-hook.sh isn't using test_set_editor
    in a comment.
  * Clarified the purpose and implementation of test_set_editor in a comment.
