From: Julia Lawall <julia(a)diku.dk>

Move the if(err) statement after the if into the if branch indicated by its
indentation. The preceding if(err) test implies that err cannot be nonzero
unless the if branch is taken.

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(a)p1 S2(a)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>
