Re: [hylafax-users] fatal error on formfeed

[Glenn Burkhardt <glenn@aoi-industries.com>]

Ok, here's a better patch for 'textfmt'.  This one yields fewer blank pages - 
a file that ends in a formfeed produces the same number of pages that a file 
omitting the formfeed does.  If a formfeed is coincident with a page break 
that's generated by 'textfmt' (this is the bug you found) because the number 
of line per page has been reached, 'textfmt' will not put in an extra blank 
page.

And, another unrelated bug is fixed - for a file that contains a single 
character, with no linefeed at the end.
