Default message about already patched files is too verbose #19

What steps will reproduce the problem?
1. run patch.py two times

What is the expected output? What do you see instead?
file 4/4:    templates/issue.html
 hunk no.2 doesn't match source file at line 203
  expected:       <input type="hidden" name="subject" value="{{issue.subject}}" />
  actual  :       <input type="hidden" name="in_reply_to" value="" />
already patched  templates/issue.html

this can be replaced with something like

file 4/4:    templates/issue.html
already patched  templates/issue.html

or even

file 4/4 already patched:    templates/issue.html
