Fix: Missing spaces in printed messages

Several messages are printed with the `print` method and the message
is split across two lines, i.e.:

 print('This is a message split'
       'across two source code lines')

Which causes the message to be printed as:

 This is a message splitacross two source code lines

Add a space at the end of the first line before the line break:

 print('This is a message split '
       'across two source code lines'

Also correct a minor spelling mistake.
