Merge condition for more readable code

[monperrus]

When you have twice the same condition in the same block it can be merged:

if (a!=null) {
  a.foo();
}
somethingeslse();
if (a!=null) {
  a.bar();
}

becomes

if (a!=null) {
  a.foo();
  somethingeslse();
  a.bar();
}

(bug found with Repairnator)

For me it is not automatic, it will depends of somethingeslse();
But it can be a new repair model. Not so easy to implement in a meta-program.

Not so easy to implement in a meta-program.

I agree. I would see this more as a postprocessing of patches.

Yes, or a validation with a pure template mode.
