Re: how to restrict the numbers of chars in a buffer/file

Hello
Is there any possibility that a given buffer/file only admits say 150
chars but not more?
`after-change-functions' is a simple built-in variable.
Value: nil
Documentation:
List of functions to call after each text change.
Three arguments are passed to each function: the positions of
the beginning and end of the range of changed text,
and the length of the pre-change text replaced by that range.
(For an insertion, the pre-change length is zero;
for a deletion, that length is the number of characters deleted,
and the post-change beginning and end are at the same place.)
Buffer changes made while executing `after-change-functions'
don't call any before-change or after-change functions.
So cut down any changes to 150 characters here.
