A bin/upload_module.pl So by here, we know that the commit only affects that single file. No funny stuff like mode changes of other files. > (stable) $ git cherry-pick 301afce1 > Finished one cherry-pick. > www/client/css/admin-clean.css: needs merge > www/client/css/admin.css: needs merge > www/client/css/error.css: needs merge > www/client/css/public.css: needs merge > www/client/css/user-clean.css: needs merge > <...snip> > www/client/css/admin-clean.css: unmerged > (832c41e99d19f2dd39c9cf3709f14619ffab24b8) > www/client/css/admin.css: unmerged > (8e7cd850bf40d1a921b1f62ce0945abd374fa55d) > www/client/css/error.css: unmerged > (88945d05640c0820c9cf68922392573d4ac07b2c) > <...snip> > ... > error: Error building trees Then, wham, these files want to be changed.

The answer (or at least a bug triage) should be in the output of those commands. You can reproduce exactly the merge by making a new branch at the position where you were attempting to land the cherry pick before, and checking that branch out. One last test, would be to check that it happens on a clean clone of the repository. I don't think that you're hitting any repository-local behaviour (eg, the ability to mark certain files as "always ignore") but you never know. These commands are all being run on the same working copy, right?
