Fix a large number of typos and other problems (#110)
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: https://github.com/att/ast/issues/764 - Fixed a bug in the man page that caused searches for the '|' character to fail. Bug report: https://github.com/att/ast/issues/871 - Removed a duplicate description of 'set -B' from the man page. Bug report: https://github.com/att/ast/issues/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: https://github.com/att/ast/issues/948 https://github.com/att/ast/issues/503#issuecomment-386649715 https://github.com/att/ast/issues/507#issuecomment-507924608 - Applied the following ksh2020 documentation fixes: https://github.com/att/ast/pull/351 https://github.com/att/ast/pull/352 - Fixed a minor GCC -Wformat warning in procopen.c by changing a sentinel to NULL.
