Mod 20 6 Apr 79 -- Changed 12-pitch DTC terminals to still space 1/6 inch (instead of 1/8 inch), unless the 'x' register is non-zero -- doable with the -rx1 option on the nroff command line. Mod 19 28 Mar 79 -- Had .ep do a .rs, to avoid occasional problems (like with .+c (again). -- Added the 'X' register: if non-zero on startup on a 12-pitch terminal, it outputs 6 LPI instead of 8 LPI. Mod 18 26 Mar 79 -- Had .+c reset indent, to solve problems of prelim material after a .ip (as with references) Mod 17 19 Mar 79 -- Fixed a bug in .++ which caused it to renumber pages incorrectly, the result of nroff starting a new page immediately upon reaching the end of the previous page (damn!). Mod 16 8 Mar 79 -- Fixed a bug in .++ which caused it to change page number formats before forcing out the page. -- Changed tmac.e so that extra '.so's to the package will next to 'null.me'. -- Changed .sh so that a title of "_" will cause section depth change side-effects only (base indent will remain the same, and no output will occur). Mod 15a 7 Mar 79 -- Fixed a bug in Mod 15 which caused .ip's to fail. Mod 15 2 Mar 79 -- Changed .@p to do paragraph indents normally in keeps, which will override the indent parameter in keeps with paragraph forms in them (use .ba to fix this). Mod 14 23 Feb 79 -- Fixed .ip so it would hyphenate correctly. Mod 13 16 Feb 79 -- Added .rs before eqn title output to fix vertical centering problem. Mod 12 15 Feb 79 -- Changed NROFF bold font to be regular .ul (.cu is a pain). -- Changed .sh to output regular spaces instead of unpaddable spaces. -- Fixed bug in .1c with bad line length (didn't reset \n($l). Mod 11 13 Feb 79 -- Added hook to .$c to call .$C (for index entries or whatever). Mod 10 12 Feb 79 -- Had .xp print in current environment and not reset to single spacing, to allow more control over output format. Mod 9 26 Dec 78 -- Fixed yet another problem with equation spacing. Mod 8 18 Dec 78 -- Fixed .@q to solve a problem with \n(dn getting lost on equations at top of page. Mod 7 11 Dec 78 -- Had .@q (equation output) move to end of equation after equation output (eqn doesn't seem to space quite right). Mod 6 27 Nov 78 -- Fixed the umlaut on DTC output to be prettier. Mod 5 5 Nov 78 -- Fixed a bug with the second parameter to .ip. Mod 4 2 Nov 78 -- Added .uh command (unnumbered heading). -- Changed .$p and .sh accordingly. Mod 3 2 Oct 78 -- Fixed .ne command in .$p (print section headings). Mod 2 25 Sep 78 -- Changed .np to use () instead of []. Mod 1 12 Sep 78 -- Fixed footnote fudge factor (curse NROFF!!) -- Put "needs" on .(z, .)z. Mod 0 11 Sep 78
