roff(7) dictates that "Each sentence should terminate at the end of an
input line." Instead of doing this, Sortix manpages (incorrectly) used
double-spaces to separate sentences.
Additionally, fix a few small typos.
The console has gained these escape codes:
- Set color to any of 256 entries in the palette.
- Set color to any 24-bit RGB value.
- Inverse mode.
- Bold mode.
- Underline mode.
- Move cursor to line N.
- \a is now ignored.
The effectively unused ATTR_CHAR has been removed. Parsing of escape codes
has been improved. The graphical palette has been changed to the tango
colors, which makes Sortix look a bit differently. Some user-space programs
have been changed to use different colors that look better under the new
palette.
Remove const from methods that weren't really const and remove mutable
keyword workaround.
A new ioctl TIOCGDISPLAYS allow detecting which displays the terminal
has associated. The ability to set a keyboard layout can be detected
with tcgetblob kblayout.
Improve the user-space multi-monitor support while here.
The kernel now sets TERM rather than init(8).
This is a compatible ABI change riding on the previous commit's bump.
This change refactors the process group implementation and adds support
for sessions. The setsid(2) and getsid(2) system calls were added.
psctl(2) now has PSCTL_TTYNAME, which lets you get the name of a process's
terminal, and ps(1) now uses it.
The initial terminal is now called /dev/tty1.
/dev/tty is now a factory for the current terminal.
A global lock now protects the process hierarchy which makes it safe to
access other processes. This refactor removes potential vulnerabilities
and increases system robustness.
A number of terminal ioctls have been added.
This is a compatible ABI change.
execl(3) and its variants use a sentinel to terminate the variadic
argument list, in the form of a null pointer constant of type pointer to
char. POSIX mandates that NULL is a null pointer constant of type
pointer to void, which is not of an equivalent type to that required by
execl(3) and its variants, resulting in undefined behaviour.
This commit casts all such instances of NULL to pointer to char type.
For consistency, it also adds const-qualification to any such instances
which had already been casted, and were not const-qualified.

New options:
-1 Disable columnizing.
-c Sort by file status change time.
-C Column directory entries.
-h Show file sizes with magnitude suffixes such as 42.3K.
-r Sort entries in the opposite order.
-R Recursively list directory contents.
-S Sort by file size in decreasing order.
-u Sort by access time.
--color=always|auto|never
Control whether colorizing is enabled.
The output is now natively columnized instead of running a column(1)
subprocess. Multiple operands are now implemented correctly (directory
contents are columned separately rather than their concatenation, the name
of each directory is printed prior to its content, ...). The file owner and
group names are now shown rather than a hard-coded root. Long listings are
now properly aligned. Mixing file and directory operands works correctly
now. Columnizing is now vertical rather than across. Clean up the source
code and remove cruft. Stat information on directory entries are read once
only now, which which fixes an incosistent sort race condition when sorting
according to lstat. Move to the openat paradigm.
Options and escape sequences are fatally incompatible with historic echo
that has no room for such extensions. Instead they pose risk because it is
harder to use echo on unvalidated input safely and because any further
extensions potentially break existing scripts. Use printf(1) instead.
I originally left them out because Sortix doesn't have setuid and setgid
executable support, but this created considerable compatibility issues and
it is better to supply them as the mode bits still exist and can be set.
