    fmt_txt.pl: Put txt output in a single large page. 99999 lines should be enough. (#3180)
    
    There were unpredictable gaps between some environments in txt output.
    This looks like a page-break related problem, seems that with previous
    code groff is breaking pages in a supposedly continuous text output,
    and things are joined in a page-break.
    
    We make sure that groff thinks page is a really large single page, so
    the above does not happen. Implemented method was explaind in Groff
    mailing list by Anton Shepelev.
    
    First, we set a really large page length and instead of explicitly
    resetting pagelength at the end if the file, just use an end-of-input
    trap to set the real page-length in the end.
