So essentially I have myself a nice working copy of OF-2.2.2
I'm writing my own applications and libraries in my OpenFOAM/user-2.2.2/... directories, and all is well.
I'm referring to the original source files in OpenFOAM/OpenFOAM-2.2.2/src/... directories.

My question is, whilst I have these open in an editor to refer to, sometimes I make changes to the original /src files, which I don't want to do, and accidentally save them. Usually I notice, undo the changes, and save them again, but I'm worried I might change the source files, save them, and not notice. Now until I wmake in the src directories, this won't change my installation (right?) and so shouldn't matter, but it does mean that I might later be referring to source files which are not as they originally were.

Is it safe to type

cd src
sudo chown -R root *

such that then the directories under the src directory have permissions like (viewed via ls -l)
