Subject: Make C++ buffers writeable when writing their initial text properties.
X-Git-Tag: emacs-25.0.90~263
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=229c3fa;p=emacs.git

Make C++ buffers writeable when writing their initial text properties.

This is a correction to yesterday's CC Mode patch.

* lisp/progmodes/cc-engine.el (c-before-change-check-<>-operators): Put
c-save-buffer-state around the function rather than a mere `let'.
