Resolves 5009
For loops represented by a ControlFlow object use " in" as their connector.
rustfmt searches for the first uncommented occurrence of the word "in" within the
current span and adjusts it's starting point to look for comments right after that.
visually this looks like this:
rustfmt starts looking for comments here
|
V
for x in /* ... */ 0..1 {}
This works well in most cases, however when the pattern also contains
the word "in", this leads to issues.

|
V
for in_here in /* ... */ 0..1 {}
-------
pattern
In order to correctly identify the connector, the new approach first
updates the span to start after the pattern and then searches for the
first uncommented occurrence of "in".
