Subject: Re: Removing line and column number settings from some buffers

Message-ID: <trinity-164bdcea-ca22-4249-8cb8-9114a7d67f9e-1607143352945@3c-app-mailcom-bs04> (raw)

Have tried using your suggestion. The file is being created
with the correct information. However, when the code gets to
option 3, the Mode Line is not being reverted to its original
state.
