Modified Files:
src/usr.bin/env: env.1 env.c
Log Message:
Implement env(1) -u
The option '-u name' causes removal of the name environment variable if
it is in the environment. This is similar to the unset command in sh(1).
The value for name must not include the '=' character.
Add HISTORY section in the man page.
The -u argument is implemented by Linux, FreeBSD and Darwin.
The lack of -u in NetBSD is a cause for a frequent fallout in the LLVM
toolchain test-suite.
