The script calls checkpatch.pl on each file, and formats any error messages
to comply with standard compiler error messages:
file_name:line_number:error_message
This is particularly useful when run from within a text editor which can
parse these error messages and show the user a buffer with the file in
question, placing the cursor on the offending line (e.g., Emacs's "M-x
next-error" command, bound by default to C-x `).
