xdiff: fix merging of hunks with -W context and -u context
If the function context for a hunk (with -W) reaches the beginning of the next hunk then we need to merge these two -- otherwise we'd show some lines twice, which looks strange and even confuses git apply. We already do this checking and merging in xdl_emit_diff(), but forget to consider regular context (with -u or -U). Fix that by merging hunks already if function context of the first one touches or overlaps regular context of the second one.
