Package: Emacs
Version: 23.0.60
Severity: wishlist

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Write a revert-buffer that uses something like `diff' and then applies
the patch to the buffer, so as to better preserve markers and undo info.
This would be used in places where a revert-buffer is needed but the
changes are expected to be small, e.g. in VC.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/home/monnier/src/emacs/work/etc/DEBUG for instructions.
