Add a Checkstyle rule that prohibits spaces in `for (;;)` (#1599)
Add a Checkstyle rule that prohibits spaces in `for (;;)` (#1599)

Motivation:

IntelliJ inserts unnecessary space between semicolons in `for (;;)`
making the `for` sentence look weird when reformatting or re-indenting:

    for (; ;) { ... }

.. and I'm tired of adding comments for this kind of aesthetical issue.

Modifications:

- Add a Checkstyle rule that prohibits spaces in `for (;;)`

Result:

- Automation
