That would be nice, to use presubmit_canned_checks.PanProjectChecks instead of
duplicating a lot like below!
See
https://cs.chromium.org/chromium/tools/depot_tools/presubmit_canned_checks.py...

[nisse-webrtc, 2016/09/01 13:32:06]

I'd need some more detailed guidance if you want me to do that in this cl, I'm
not familiar at all with the presubmit logic.

[kjellander_webrtc, 2016/09/01 13:49:15]

No let's do it in the future. I filed
https://bugs.chromium.org/p/webrtc/issues/detail?id=6292 to track that.

   # WebRTC can't use the presubmit_canned_checks.PanProjectChecks function since
   # we need to have different license checks in talk/ and webrtc/ directories.
   # Instead, hand-picked checks are included below.
 
   # .m and .mm files are ObjC files. For simplicity we will consider .h files in
   # ObjC subdirectories ObjC headers.
   objc_filter_list = (r'.+\.m$', r'.+\.mm$', r'.+objc\/.+\.h$')
   # Skip long-lines check for DEPS, GN and GYP files.
   build_file_filter_list = (r'.+\.gyp$', r'.+\.gypi$', r'.+\.gn$', r'.+\.gni$',
