If I'm in the middle of typing a line of code and I
press "page up" or "page down" once (or many times) in
order to refer to code a few pages away, it would be
nice if the cursor would return to exactly the same
column prior to me pressing page up or page down.
Currently it seems the default behaviour is to place
the cursor at the beginning of the line whenever page
up or page down is pressed.
I understand the latter (current) behaviour may be
preferred by some, so, if this change were to be
introduced, it seems it would be best to implement it
as an option.
