[PATCH 0/6] test: make the test suite work with zsh

It's not difficult to make the testing library work for zsh, so I did that in the first patch.

The rest of the patches are basically to deal with some variables that are special in zsh, workaround a bug, and a minor discrepancy.

Felipe Contreras (6):
  test: fix build for zsh
  test: avoid `stat` variable
  test: avoid `options` variable
  test: avoid `path` variable
  test: hack for zsh
  mergetools: vimdiff: check for empty fields
