FakeVim: git log can be modified

Steps to reproduce:

• have a project open with underlying repository
• display git log for the project
• in FakeVim mode try to delete characters, lines or modify something directly from command mode (upper case..) or similar
  (dd, x, ~, U, u, yy followed by p, ....)

Note: in Insert/Replace mode the readonly character of the vcs log widget seems to be honored and modifications aren't possible.
