Restore read-only attribute for .rc or .vbp files after set version option

[AlexB]

I can't agree with it.
If I want to commit the version change I have to check the file out before (and delete read-only attribute) and check it in after compilation.

And I can't reset read-only attribute because I don't know if this file was writeable or no before (or I need to save the attribute before).

In my case I don't want to commit version change to source control.

In all cases it is dangerous to modify readonly attribute outside of source control system. Now I get situation when there is writeable checked in file.

IMHO VBP must restore readonly (in other words - doesn't change readonly attribute).
Thanks.
