Tab completion changes after Ctrl+C

[smcintyre-r7]

After Ctrl+C has been issued to msfconsole, the tab completion options start to append a space at the end of words which makes it very difficult to continue tab competing the rest of the path.

Steps to reproduce

1. Start msfconsole
2. Type use exp and hit tab, see it expand to use exploit/ (no trailing space, ready to complete more)
3. Hit Ctrl+C
4. Type use exp and hit tab, see it expand to use exploit/ (trailing space, completion terminated)
