With staticLogFileName true, a date pattern that formats as a short number (.dd, .MM, .HH, .yyyy) names dated files like numbered backups: log.txt.10 is both the file for the 10th and backup 10, so rolling one can overwrite the other. Affects Composite rolling, and Date rolling with appendToFile false.

Split out of #334.
