[RFC PATCH 0/3] diff --color-moved-ws: allow mixed spaces and tabs in indentation change

From: Phillip Wood <redacted>

When trying out the new --color-moved-ws=allow-indentation-change I
was disappointed to discover it did not work if the indentation
contains a mix of spaces and tabs. This series adds a new option that
does. It's and RFC as there are some open questions about how to
proceed, see the last patch for details. Once there's a clearer way
forward I'll reroll with some documentation changes.

Phillip Wood (3):
  xdiff-interface: make xdl_blankline() available
  diff.c: remove unused variables
  diff: add --color-moved-ws=allow-mixed-indentation-change
