lftp option -c doesn't exist

Hello everybody, I just joined to report an issue I've found on lftp, I
hope this is the right place.

Searching the list's archives I've found this only email:

http://www.mail-archive.com/lftp-devel%40uniyar.ac.ru/msg01598.html

which does not have any reply and is more than a year old.

I've found the same issue, that is, lftp doesn't honour the '-c' option
which is documented, so one has to do something like this:

lftp -e 'ls; quit' ...
instead of this
lftp -c 'ls' ...

It's a minor nuisance, but still...

The same problem occurs in lftp v3.6.1-1 on an ubuntu machine, also v3.7.3
on an arch machine and also on v3.5.6-1 on a debian one.

I believe the problem is easy to solve, but I haven't checked the source
so far. Are there any plans in the near future to solve it or this is just
a forgotten no-one-cares-thingy?
