Subject: [PATCH 36/42] tools/perf: Adjust confusing if indentation

From: Julia Lawall <[email protected]>

Outdent the code following the if.

The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@r disable braces4@
position p1,p2;
statement S1,S2;
@@

(
if (...) { ... }
|
if (...) S1@p1 S2@p2
)

@script:python@
p1 << r.p1;
p2 << r.p2;
@@

if (p1[0].column == p2[0].column):
cocci.print_main("branch",p1)
cocci.print_secs("after",p2)
// </smpl>

This patch does not change the semantics. But it might not be the correct
fix either.
