if ($_ !~ /^[\(\[\{]/ && $_ =~ /^(\S+)/) {
print "@@ -a,b +c,d @@ $1\n"
}
So
label:
will be the 'mark[er]' for the @@ line
Just try yourself:
<<< foo.c <<<
int main(void)
{
x
y
z
label:
a
b
c
d
e
f
}
>>>
<<< foo2.c <<<
int main(void)
{
x
y
z
label:
a
b
c
d
d+
e
f
}
>>>
<<< diff -dpru foo.c foo2.c <<<
--- foo.c 2007-05-30 10:33:45.714222656 +0200
+++ foo2.c 2007-05-30 18:03:43.061471495 +0200
@@ -8,6 +8,7 @@ label:

e

}
