Author: gahr (ports committer) Date: Wed Oct 26 08:39:33 2016 New Revision: 307958 URL: https://svnweb.freebsd.org/changeset/base/307958 Log: MFC r307638: Chase a cornercase in printenv and sync its behaviour with builtin's The cornercase is when printenv is passed a parameter in the form VAR=val, where VAR=val exists in the environment. In this case, printenv would print a spurious newline and returns 0.
