Merge #2392
2392: Fix panic during the expansion of `column!` r=edwin0cheng a=marcogroppo
Fixes #2379. Well, this isn't the "proper" fix but it doesn't hurt, IMHO.
The problem is that `to_col_number`, called by `column_expand`, receives a position number that isn't included in the text range of the file. My (very limited) understanding is that the text is the one of the original file, while `pos` is relative to something else, probably the text of the macro. Notice that in this case the `column!` expansion seems to be triggered by `assert_eq!`, so we're in the middle of another expansion. This PR simply avoids the panic by checking the length of the text.
