This commit makes various different improvements to the documentation:
- sh.1: Backported (with changes) mandoc warning fixes from ksh2020
for the ksh93(1) man page: <https://github.com/att/ast/pull/1406>
- Removed unnecessary spaces at the end of lines to fix a few other
mandoc warnings.
- Fixed various typos and capitalization errors in the documentation.
- ANNOUNCE: Document the addition of the ${.sh.pid} variable
(re: 9de65210).
- libast/man/str*: Update the man pages for the libast str* functions
to improve how accurately each function is described.
- ksh93/README: Update regression test/compatibility notes to include
OpenBSD 7.0, FreeBSD 13.0 and WSL running Ubuntu 20.04.
- Change a few places to store the return value from strlen in a
size_t variable rather than signed int.
- comp/setlocale.c: To avoid confusion of two separate variables named
lang, the function local variable has been renamed to langidx.
