It took about 1 second to realize that "80 characters" and "unlimited" aren't the only two options.
I was definitely NOT thinking of unlimited.
I was thinking of 80chars, but excluding numerals (123, etc) and number text ("thousand", "million" etc.) and maybe a few other items excluded from the count, with a maximum of 100, or whatever number actually will not break the layout.
I've found it frustrating trying to fit in 80chars, and e.g., finding that ampersand gets expanded so it actually counts more than "and", so it is not a single-rule 80 chars; perhaps a few more sophisticated rules might help. Just a suggestion.
