If I add a comment in Stash’s code review interface that contains something like this:
[csMutable addCharactersInString:@"-"];

It turns it into this:
[csMutable addCharactersInString:@-];

And if I try doing something more complicated, like this:
@[@“foo”, @“bar”, @“baz”];

It results in a comment like this:
@[@foo, @bar, @baz];

This is really annoying and makes code review of Obj-C sources a real pain.
