CONTINUATION_ALIGN_STYLE does not respect USE_TABS

[clayote]

I'm switching my project from space indentation to tabs using yapf USE_TABS = True.

Some of the existing code deals with overlong lines using backslashes

bar = {'baz': {'qux': {'quux': ''}}}
bar['baz']['qux']['quux'] \
   = 'foo'

I want the second line to be indented with one tab, rather than the three spaces it currently is, so I set CONTINUATION_ALIGN_STYLE = VALIGN-RIGHT

Yet, yapf leaves this block of code as-is.

I actually tried just switching that block to tabs manually, and yapf doesn't seem to respect that either? It turns it back into spaces.
