Prompt string do not show until ^C combination

[oshnix]

After each input I should press ^C to get "User input: " prompt string and if I do not do it - all my input would be just ignored.
It looks like this:

User input: \contacts
        id        mutual    name                              username
        ...
^C
User input:

Also it would be great to add completion for:

• commands (\c => \commands)
• user id's \umsg

\umsg <TAB>
1 - user1
2 - user2
3 - user3
\umsg

Changing user id's input on usernames input would be also cool.
