Strip trailing spaces off guessed target directory in builtin clone, and replace 'control' characters with an ASCII space.

User still can have any name by specifying it explicitely after url.

This should take care of accidental pastings inside shell quotes. At least for the local part of the operation. Now I'm looking at the code and think I should have stripped the heading whitespace as well. It is much less likely to happen, though.
