Index: src/tbl/t7.c Fix Description: The "tbl" command may output a troff ".ne" directive that's larger than the size of the table being produced. Repeat-By: Create a file with these lines (eliminating the leading indent): echo ' .TS box ; l l . x _ _ x .TE ' | tbl | fgrep .ne (Note that the character between the two underscores above is a tab.) Now run the file through "sh" and note the result: .ne 3v+0p Next edit the above file, changing the line with the two underscores to a line with just a single underscore on it. Run the file through "sh" again and note the result: .ne 2v+2p Even though the two versions of the file produce identical-looking output when "typeset," the size that tbl claims is needed is different. Fix: Here's the fix to the 4.1bsd version of "src/tbl/t7.c". As usual, the trade secret status of the code involved precludes a clearer posting. The fix is an addition to the function "need", conditioned on "OLDVERSION": ... if (instead[i]!=0) continue; else #ifndef OLDVERSION if (allh(i)) horlin++; else #endif texlin++; ... -- Bugs is a Warner Brothers trademark.
