Example:
$ ./codespell.py -d example/dict.txt example/code.c
example/code.c:9: clas ==> class | disabled due to name clash in c++
example/code.c:10: tis ==> this
example/code.c:14: opem ==> open
example/code.c:16: buring ==> burying, burning, burin, during
example/code.c:17: clas ==> class | disabled due to name clash in c++
When checking patches instead of files, it's better to have the patch in
stdin and dict always as a file. Checking stdin instead of a file will
be added later.
