+\S{faq-missing-slash}{Question} PSFTP commands seem to be missing a
+directory separator (slash). 
+
+Some people have reported the following incorrect behaviour with
+PSFTP:
+
+\c psftp> pwd
+\e        iii
+\c Remote directory is /dir1/dir2
+\c psftp> get filename.ext
+\e        iiiiiiiiiiiiiiii
+\c /dir1/dir2filename.ext: no such file or directory
+
+This is not a bug in PSFTP. There is a known bug in some versions of
+portable OpenSSH
+(\W{http://bugzilla.mindrot.org/show_bug.cgi?id=697}{bug 697}) that
+causes these symptoms; it appears to have been introduced around
+3.7.x. It manifests only on certain platforms (AIX is what has been
+reported to us).
+
+There is a patch for OpenSSH attached to that bug; it's also fixed in
+recent versions of portable OpenSSH (from around 3.8).
