Subject: [PATCH 1/2] xdiff/xprepare: use the XDF_DIFF_ALG() macro to access flag bits

From: Ramsay Jones <[email-masked]>
Date: Fri, 4 Mar 2016 23:09:36 +0000

Commit 307ab20b3 ("xdiff: PATIENCE/HISTOGRAM are not independent option
bits", 19-02-2012) introduced the XDF_DIFF_ALG() macro to access the
flag bits used to represent the diff algorithm requested. In addition,
code which had used explicit manipulation of the flag bits was changed
to use the macros.

However, one example of direct manipulation remains. Update this code to
use the XDF_DIFF_ALG() macro.
