util/lint: Give better warning for help spacing issue

Because the help block uses significant whitespace to determine whether
or not text is inside the help block, a mixture of spaces and tabs
confuses the parser.
If there's an unrecognized line, and the previous line was inside a help
block, it's likely that this line is too.

Additionally, this was found with a line that started '  configuration',
and threw a perl warning about an uninitialized value because the parser
thought this was the start of a new config line, but couldn't find the
symbol.  Now we make sure that config statements have whitespace after
the 'config' statement.
