CVS commit: src/usr.bin/make

["Roland Illig" <rillig%netbsd.org@localhost>]

Module Name:    src
Committed By:   rillig
Date:           Tue Dec 22 20:10:21 UTC 2020

Modified Files:
        src/usr.bin/make: make.1 nonints.h var.c
        src/usr.bin/make/unit-tests: directive-undef.exp directive-undef.mk

Log Message:
make(1): allow .undef to undefine multiple variables at once

Since make doesn't support variable names containing spaces, this edge
case is not enough reason to stop this feature.  Having multiple
variable names as arguments nicely aligns with other directives such as
.for and .export.
