This is an improvement, but it would be nice if the edit did not move
the line you are editing to the end of the file.  Usually there is some
context of comments related to the variable you are setting.  The function
which edits and sets the variable should not change this.  This makes it
easier to look through the file if needed to find the line you are looking
for, to see what the settings are, and to reference the information in the
comments.
