The "env" statement is now a compound statement. It can contain four
substatements: "clear" to clear the environment, "keep" to retain
certain variable while clearing it, "set" to set a variable, and
"unset" to unset a variable or variables.
Both "keep" and "unset" can take globbing pattern as their argument,
in which case they affect all variable matching that pattern.
The value part in the "set" statement is subject to variable expansion,
e.g.
set "MANPATH=$MANPATH${MANPATH:+:}/usr/local/man"
The support for the old one-line syntax of "env" is retained for
backward compatibility.
This commit also fixes redirection to a file: new data are appended
to the file, instead of overwriting it.
