Hi!
I've noticed that sometimes an extra carriage return character pops up in my source files, when running Emacs under Windows. They are always located at the end of a line. I use auto-revert mode and I've only seen this in files already open in Emacs.
Today I noticed that one such carriage return character was placed at buffer position 62879 in line 2658. This corresponds to byte position 65536 (or hex 0x10000) in the file. Clearly, this can't be a coincidence.
By the way, I'm not sure Emacs is the culprit here -- I use subversion as a version control system and Visual Studio for debugging and sometimes minor edits.
