[PATCH v2 0/3] difftool --dir-diff test improvements

This version fixes the actual cause of the test failure (not being
specific enough when adding files).  This is done with a new version of
patch 2.

Patch 1 is unchanged and patch 3 only contains a minor change.

This is built on da/difftool-fixes.  There may be a small textual
conflict with jk/difftool-dir-diff-edit-fix in the context lines but I
don't believe there is any logical conflict.

John Keeping (3):
  t7800: don't hide grep output
  t7800: fix tests when difftool uses --no-symlinks
  t7800: run --dir-diff tests with and without symlinks
