Noteworthy changes:
- The man pages have been updated to fix a ton of instances of
runaway underlining (this was done with `sed -i 's/\\f5/\\f3/g'`
commands). This commit dramatically increased in size because
of this change.
- The documentation for spawnveg(3) has been extended with
information about its usage of posix_spawn(3) and vfork(2).
- The documentation for tmfmt(3) has been updated with the changes
previously made to the man pages for the printf and date builtins
(though the latter builtin is disabled by default).
- The shell's tracked alias tree (hash table) is now documented in
the shell(3) man page.
- Removed the commented out regression test for an ERRNO variable
as the COMPATIBILITY file states it was removed in ksh93.
Many of these changes are minor typo fixes. The other changes
(which are mostly compiler warning fixes) are:
NEWS:
- The --globcasedetect shell option works on older Linux kernels
when used with FAT32/VFAT file systems, so remove the note about
it only working with 5.2+ kernels.
src/cmd/ksh93/COMPATIBILITY:
- Update the documentation on function scoping with an addition
from ksh93v- (this does apply to ksh93u+).
src/cmd/ksh93/edit/emacs.c:
- Check for '_AST_ksh_release', not 'AST_ksh_release'.
src/cmd/INIT/mamake.c,
src/cmd/INIT/ratz.c,
src/cmd/INIT/release.c,
src/cmd/builtin/pty.c:
- Add more uses of UNREACHABLE() and noreturn, this time for the
build system and pty.
src/cmd/builtin/pty.c,
src/cmd/builtin/array.c,
src/cmd/ksh93/sh/name.c,
src/cmd/ksh93/sh/nvtype.c,
src/cmd/ksh93/sh/suid_exec.c:
- Fix six -Wunused-variable warnings (the name.c nv_arrayptr()
fixes are also in ksh93v-).
- Remove the unused 'tableval' function to fix a -Wunused-function
warning.
src/cmd/ksh93/sh/lex.c:
- Remove unused 'SHOPT_DOS' code, which isn't enabled anywhere.

src/cmd/ksh93/bltins/misc.c,
src/cmd/ksh93/bltins/trap.c,
src/cmd/ksh93/bltins/typeset.c:
- Add dictionary generator function declarations for former
aliases that are now builtins (re: 1fbbeaa1, ef1621c1, 3ba4900e).
- For consistency with the rest of the codebase, use '(void)'
instead of '()' for print_cpu_times.
src/cmd/ksh93/sh/init.c,
src/lib/libast/path/pathshell.c:
- Move the otherwise unused EXE macro to pathshell() and only
search for 'sh.exe' on Windows.
src/cmd/ksh93/sh/xec.c,
src/lib/libast/include/ast.h:
- Add an empty definition for inline when compiling with C89.
This allows the timeval_to_double() function to be inlined.
src/cmd/ksh93/include/shlex.h:
- Remove the unused 'PIPESYM2' macro.
src/cmd/ksh93/tests/pty.sh:
- Add '# err_exit #' to count the regression test added in
commit 113a9392.
src/lib/libast/disc/sfdcdio.c:
- Move diordwr, dioread, diowrite and dioexcept behind
'#ifdef F_DIOINFO' to fix one -Wunused-variable warning and
multiple -Wunused-function warnings (sfdcdio() only uses these
functions when F_DIOINFO is defined).
src/lib/libast/string/fmtdev.c:
- Fix two -Wimplicit-function-declaration warnings on Linux by
including sys/sysmacros.h in fmtdev().
These are minor fixes I've accumulated over time. The following
changes are somewhat notable:
- Added a missing entry for 'typeset -s' to the man page.
- Add strftime(3) to the 'see also' section. This and the date(1)
addition are meant to add onto the documentation for 'printf %T'.
- Removed the man page the entry for ksh reading $PWD/.profile on
login. That feature was removed in commit aa7713c2.
- Added date(1) to the 'see also' section of the man page.
- Note that the 'hash' command can be used instead of 'alias -t' to
workaround one of the caveats listed in the man page.
- Use an 'out of memory' error message rather than 'out of space'
when memory allocation fails.
- Replaced backticks with quotes in some places for consistency.
- Added missing documentation for the %P date format.
- Added missing documentation for the printf %Q and %p formats
(backported from ksh2020: https://github.com/att/ast/pull/1032).
- The comments that show each builtin's options have been updated.
Many of the errors fixed in this commit are word repetitions
such as 'the the' and minor spelling errors. One formatting
error in the ksh man page has also been fixed.
A column of whitespace in the NEWS file was removed for consistent
formatting. Most of the spelling errors were found with this
codespell dictionary:
