This patch was generated automatically by the "modeline.py" script, available here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py For every file that is modified in this patch, the changes are as follows: (1) The patch changes the file to use the exact C++ mode lines from the Mozilla coding style guide, available here: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line (2) The patch deletes any blank lines between the mode line & the MPL boilerplate comment. (3) If the file previously had the mode lines and MPL boilerplate in a single contiguous C++ comment, then the patch splits them into separate C++ comments, to match the boilerplate in the coding style.
