On this man page, ksh(1) commands that are preceded by one
or two * (asterisks) are treated specially in the following
1. Variable assignment lists preceding the command remain in
effect when the command completes.
2. I/O redirections are processed after variable assign-
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the
format of a variable assignment, are expanded with the
same rules as a variable assignment. This means that
tilde substitution is performed after the = sign and word
splitting and file name generation are not performed.
