Release 1.0.0-beta.1

In May 2020, when every KornShell (ksh93) development project was
abandoned, development was rebooted in a new fork based on the last
stable AT&T version: ksh 93u+. Now, one year and hundreds of bug
fixes later, the first beta version is ready, and KornShell lives
again. This new fork is called ksh 93u+m as a permanent nod to its
origin; a standard semantic version number is added starting at
1.0.0-beta.1. Please test the beta and report any bugs you find,
or help us fix known bugs.
