When on-disk file has changed, I use the following function to re-read
buffer:
(defun refresh-file ()
(interactive)
(revert-buffer t (not (buffer-modified-p)) t)
)
(global-set-key [f5] 'refresh-file)
I have seen (again this morning) I wind up with a corrupted buffer. It
appears a segment of the data is correct, but data has been reordered.
I'm looking at a python source file. For example, in the middle of the buffer, it
looks like the beginning of the file is inserted (sorry I no longer have
this buffer and can't be precise).
Kill buffer, and reload file, and it's fixed.
