Fixed error produced with modified off

Browse source 
Before, when pressing <C-r> in a buffer that has &modified set to 0,
repeat would produce an error:

    Error detected while processing function repeat#wrap:
    line    2:
    E21: Cannot make changes, 'modifiable' is off
    Press ENTER or type command to continue

Now, repeat checks if the buffer is modifiable before executing.
