Fix a large number of typos and other problems

Most of these fixes are for typos and extra whitespace at the
end of lines. These are the notable changes:
- Fixed a compatibility issue with how asterisks are displayed
  using certain fonts. Bug report: att#764
- Fixed a bug in the man page that caused searches for the '|'
  character to fail. Bug report: att#871
- Removed a duplicate description of 'set -B' from the man
  page. Bug report: att#789
- Added documentation for options missing from the ksh man
  page (applies to 'hist -N', 'sleep -s', 'whence -q' and
  many of ulimit's options). Bug reports:
  att#948
  att#503 (comment)
  att#507 (comment)
- Applied the following ksh2020 documentation fixes:
  att#351
  att#352
- Fixed a minor GCC -Wformat warning in procopen.c by changing
  a sentinel to NULL.
