Modify check-format to match line length coding style

Modify check-format to match line length coding style

In an effort to clarify our coding style, generally line lengths SHOULD
be no longer than 80 columns but MUST be no longer than 100 columns

Modify the check-format.pl script to account for this.

Replace the -l|--sloppy-len option (which modifies the max line length
to 84 rather than 80 cols), with -l|--strict-len which reduces allowed
line length to 80 cols from the new default 100 cols).

Also fix up a typo in the docs indicating --sloppy-bodylen has a short
-l option (its actually -b)
