all: a few more #define tricks for AIX
This should make the AIX build finally work. Fixes #400.
tmac: rename IM (italic manual) to MR (manual reference)
Suggested by G. Brandon Robinson.
fontsrv: fix handling of colored glyphs (emoji)
Drawing as white on black to produce a mask only works if the white on black is the inversion of black on white. Emoji that force use of specific colors don't respect that. Draw black on white and invert to mask separately.
tmac: introduce real manual reference macro instead of overloading IR
The overloading of IR emits magic \X'...' sequences that turn into HTML manual links. But not all such IR invocations should be manual links; those had to be written to avoid the IR macro before. Worse, the \X'...' ending the IR causes troff to emit only a single space after a period. Defining a new IM macro for manual references fixes both problems. Fixes #441.
touch: fix for OpenBSD.
This fixes https://github.com/9fans/plan9port/issues/436 This doesn't necessarily address the underlying issue: calling p9create with mode = OREAD should probably be allowed, but currently doesn't work on OpenBSD.
draw: use int for Cacheinfo x field
With very large fonts (72pt or so) I see bad cache glyphs, and this fixes it. Not entirely sure exactly which code is overflowing, but something is.
src/cmd: rm dformat
Unclear why it is here (wkj added it long ago). It has never been installed into $PLAN9/bin, so it's doubtful that anyone has ever used it. Arnold Robbins has an alternate version at https://github.com/arnoldrobbins/dformat. Fixes #421.
osxvers: use swvers -productVersion to skip one awk call
Fixes #406. Suggested by nms42.
ed(1): fix documentation for list mode
I changed from 6 to 8 digits but forgot to update the man page.
