Split the env(1) manpage off from printenv(1); there is not much point

in keeping them together. Mention that printenv is obsolescent.

+.Nm env
+.Nd set and print environment
+.Sh SYNOPSIS
+.Nm
+.Op Fl i
+.Op Ar name Ns = Ns Ar value ...
+.Op Ar utility Op Ar argument ...
+.Sh DESCRIPTION
+The
+.Nm
+utility executes
+.Ar utility
+after modifying the environment as
+specified on the command line.
+The option
+.Ar name Ns = Ns Ar value
+specifies
+an environment variable,
+.Ar name  ,
+with a value of
+.Ar value  .
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl i
+Execute the
+.Ar utility
+with only those environment values specified.
+The environment inherited
+by
+.Nm env
+is ignored completely.
+.El
+.Pp
+If no utility is specified,
+.Nm env
+prints out the names and values
+of the variables in the environment, with one name/value pair per line.
+.Pp
+The
+.Nm env
+utility is sometimes useful with the
+.Dq Li #!
+construct (see
+.Xr execve 2 ) .
+The only difference between
+.Dq Li #!/usr/local/bin/foo
+and
+.Dq Li "#!/usr/bin/env\ /usr/local/bin/foo"
+is that the latter works even if
+.Pa /usr/local/bin/foo
+is itself interpreted.
+Using
+.Nm env
+this way also allows one to reference
+.Pa foo
+without the path,
+as well as set up the environment as desired.
+.Sh ENVIRONMENT
+The
+.Nm env
+utility uses the
+.Ev PATH
+environment variable is used to locate the requested
+.Ar utility
+if the name contains no
+.Ql /
+characters.
+.Sh DIAGNOSTICS
+.Ex -std env
+An exit status of 126 indicates
+.Ar utility
+was found, but could not be executed.
+An exit status of 127 indicates
+.Ar utility
+could not be found.
+.Sh COMPATIBILITY
+The
+.Nm env
+utility accepts the
+.Fl
+option as a synonym for
+.Fl i .

+.Nm env
+utility doesn't handle utility arguments with equal (``='') signs in their
+names, for obvious reasons.
