-- Fix footnotes if no -rv flag specified
-- Assume non-C/A/T typesetters -- use -rv2 to get old function
-- Always go into fill mode in .sh; necessary to get output format
-- Drop basic unit scaling on .sz and .ps requests; this confuses some
-- Merge ditroff and troff versions.
-- Add support for pic, gremlin, and ideal.
-- Add .lh macro to print a letterhead.
-- Adjust .bi (bold italics) to be more device resolution independent.
-- Allow .]< to initialize refer macros (as well as .]-).
-- Fix incorrect comment strip in $p macro.
-- Drop into fill mode in .TS so that text boxes will work properly.
-- Change \*- macro from \- to \(em in troff.
-- Change block indent (\n(bi) from 4n to 4m to look better in troff.
-- Don't reset ii register in .bu or .np
-- add .bu and .sm macros (bullet and smaller).
-- have .np take a fixed .ip width.
-- Avoid cut marks on laser printers.
-- Some bug fixes as reported from many places.
-- Minor improvements from rrh.
-- Fix a name conflict between .sh and floating keeps (as suggested
-- Integrate the refer macros into -me. This is basically a cheap
and dirty modification of the -ms version, and is probably not
terribly compatible with the usual -me standards. This can be
-- Allow the -rb<x> flag to set the font you want for bold font --
set it to font <x>. Default 2 (italic) in nroff, 3 (bold) in
-- Remove silly "." at top of page on dumb terminals -- lpr is smarter
-- Fixed indexes to indent on second line.
-- Improvement to nested index solution, now works for ()b & ()z.
-- More stuff to make indices inside keeps work correctly.
-- Had .)c do a .br to insure that the final line is forced out.
-- Fixed problem introduced by 2.2 which occured in footnotes and
index entries in filled keeps
-- Changed umlaut to not be so tricky -- it seems to backfire.
-- Fixed bug in indices caused by 2.2.
-- Fixed bug in footnotes caused by 2.2.
-- Changed temp file names that macros that do dynamic loading rename
themselves to. For example, if you say '.TS ... .(f' when both of
them have been used for the first time, the @T macro got used twice.
-- Suspended footnote & index processing until final output
(so that they will work properly in keeps).
-- Release 2. No changes.
-- If \nv is set on entry, handle .po differently (for vtroff).
-- Put in a cludge to try to make multi-columned output work
with wide floating keeps. Moves all wide keeps to the top
-- Fixed footnote bug that caused the first line of footnotes
that were broken across a page to be indented.
-- Fixed footnote bug that caused footnotes invoked at the
top of pages to come out in bold font.
-- Fixed equation bug that caused equations at the top of
page to be improperly centered.
-- Changed delimiter in all \w's to " from ', to allow for
-- Increased footnote fudge factor.
-- Changed \x factor in \*[ & \*< to be one half previous value.
-- Changed .ip to start new line if the tag is too long for
-- Changed .ac to handle new paper (with second parameter
-- Changed \*[ and \*< to use \x -- to avoid line overlap.
-- Changed 12-pitch DTC terminals to still space 1/6 inch (instead
of 1/8 inch), unless the 'x' register is non-zero -- do-able with
the -rx1 option on the nroff command line.
-- Had .ep do a .rs, to avoid occasional problems (like with
-- Added the 'X' register: if non-zero on startup on a 12-pitch
terminal, it outputs 6 LPI instead of 8 LPI.
-- Had .+c reset indent, to solve problems of prelim material
after a .ip (as with references)
-- 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!).
-- 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
-- Changed .sh so that a title of "_" will cause section depth change
side-effects only (base indent will remain the same, and no output
-- Fixed a bug in Mod 15 which caused .ip's to fail.
-- 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).
-- Fixed .ip so it would hyphenate correctly.
-- Added .rs before eqn title output to fix vertical centering
-- Changed NROFF bold font to be regular .ul (.cu is a pain).
-- Changed .sh to output regular spaces instead of unpaddable
-- Fixed bug in .1c with bad line length (didn't reset \n($l).
-- Added hook to .$c to call .$C (for index entries or whatever).
-- Had .xp print in current environment and not reset to single
spacing, to allow more control over output format.
-- Fixed yet another problem with equation spacing.
-- Fixed .@q to solve a problem with \n(dn getting lost on
equations at top of page.
-- Had .@q (equation output) move to end of equation after
equation output (eqn doesn't seem to space quite right).
-- Fixed the umlaut on DTC output to be prettier.
-- Fixed a bug with the second parameter to .ip.
-- Added .uh command (unnumbered heading).
-- Changed .$p and .sh accordingly.
-- Fixed .ne command in .$p (print section headings).
-- Changed .np to use () instead of [].
-- Fixed footnote fudge factor (curse NROFF!!)
-- Put "needs" on .(z, .)z.
