As a further historical note, while classical troff lacked a mechanism for specifying the amount of additional inter-sentence space, it _did_ add such space, and seemingly with the same (subpar) algorithm that this bug report bemoans: stretching inter-word spaces without restriction but keeping the size of additional inter-sentence spaces fixed. That is, running classical troff on the input file attached to _comment #4 of bug #54101 _ produces four lines of output identical to one another -- because the second parameter to .ss is ignored -- but the same problematic spacing as in groff's output, where spaces between sentences are only infinitesimally wider than those between words. (The difference is really not even detectable to the naked eye; you have to measure it.) _______________________________________________________ Reply to this item at: _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
