When applying a patch using git am test.patch, if author consists of 1 or 2 letters, then it is being replaced with author email instead. For example take patch with such line: From: AA <git@xxxxxxxxxxxxxx> Upon applying such patch, the author is replaced with email: Author: git@xxxxxxxxxxxxxx <git@xxxxxxxxxxxxxx> I did try multiple different 1 or 2 letter names, they all seem to have the same issue. 3 letter names work fine. This was tested by 3 people in our project, and happens in very different setups. I'm having a hard time finding the exact cause of it. Tried searching for issues, but didn't find anything. Maybe someone has an idea what could it be caused by? I hope I disabled the HTML mode properly and use this mailing list as intended :)
