(GEP-225) Comments starting with long white space kills formatter

A comment that starts with a very large number of white space
characters (goes beyond max width) puts the comment formatter
into an endless loop since it attempts to retain the original
indent while wrapping to width. This commint ensures that such
comments are wrapped correctly by enforcing a reasonable
indent (32 character or widht - 8 characters max).
