These are minor things I accumulated over the last month or so.
Notable changes:
src/lib/libast/features/api,
src/lib/libast/misc/state.c,
src/lib/libast/comp/conf.tab,
src/cmd/ksh93/include/defs.h:
- Bump internal libast version to 20220101L. We've made a few
additions to the API, at least pathicase (see 71934570, ca3ec200)
and astconf_long (see c2ac69b2), so this should have been done
already. This also updates '/opt/ast/bin/getconf _AST_VERSION'.
- Use AST_VERSION instead of outdated _AST_VERSION.
- In state.c, use AST_VERSION instead of hardcoding the version.
src/cmd/ksh93/sh/xec.c:
- Remove 'restorefd' variable, unused as of 42becab6.
- Remove 'cmdrecurse' function and SH_RUNPROG macro; this was once
used by a few libcmd commands, but ast-open-archive reveals it's
unused as of ast 1999-12-25.
src/cmd/ksh93/sh/*.c:
- Where available, use e_dot instead of "." for consistency; it is
defined as an extern so we might as well use it.
src/cmd/ksh93/tests/*.sh:
- When reporting signal names in fails, include the SIG prefix.
- Fix a broken process hang test in subshell.sh.
src/lib/libast/man/sfdisc.3:
- Removed. The interfaces described here never made it out of AT&T;
they do not exist in any libast version in ast-open-archive.
