lftp bug fix update

An updated lftp package that fixes various bugs is now available.

LFTP is a sophisticated file transfer program for the FTP and HTTP
protocols. Like bash, it has job control and uses the readline library for
input. It has bookmarks, built-in mirroring, and can transfer several files
in parallel. It is designed with reliability in mind.

This updated lftp package includes fixes for the following bugs:

* using the "nlist" command on an empty remote directory caused lftp to
disconnect the FTP connection. With this updated package, "nlist" works as
expected with empty directories and no longer causes a disconnection, thus
resolving the issue. (BZ#358181)

* over connections with high latencies, lftp would continued sending
"nlist" commands to the server more often than necessary, which could have
caused data transmission problems, and required extraneous bandwidth use.
(BZ#481729)

* using the "mput" command, usually with a wildcard character, to transfer
a huge number of files, such as between 20,000 and 40,000, resulted in
abnormally high CPU usage. With this updated package, transferring a huge
number of files does not cause a large increase in CPU usage, thus
resolving the issue. (BZ#433640)

All users of lftp are advised to upgrade to this updated package, which
resolves these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
