CVS commit: src/usr.bin/ftp

["Robert Elz" <kre%netbsd.org@localhost>]

Module Name:    src
Committed By:   kre
Date:           Mon Nov 20 21:11:37 UTC 2017

Modified Files:
        src/usr.bin/ftp: cmds.c ftp_var.h util.c

Log Message:
Issue PWD commands to the server only when we actually
need the results, not speculatively, just in case we might.

Allows operation with some broken servers that get confused
by PWD commands in some situations, and saves server round
trips in the (modern) common case of
        ftp ftp://path/name
where we never need to know the results from PWD.
