commit 0cb85e920666e8a47cb74ce96711fdcae8168862
Author: Guillaume Munch <[email protected]>
Date: Wed Mar 1 22:03:44 2017 +0100
Disable edition when external modifications are detected
Introduce a distinction between being read-only and having the read-only
flag. A
buffer is read-only if either it has been externally modified or if it has
the
read-only flag.
