Patch for lftp 3.7.14

[Ganael LAPLANCHE]

Hi everybody,

(originally posted to lftp@, but lftp-devel@ seems to be better, so this is a
kind of repost)

On FreeBSD, the 'help' command makes lftp 3.7.14 dump core. Here is a patch to
fix that issue. My previous patch (sent to lftp@) was missing a final endline
character.

Best regards,
