Certainly not.  You are playing with words here: choosing to display the file
is, yes, under direct user request.  That does not mean that choosing to add its
name to the history is under direct user request.

A user requesting that a given file be displayed is one thing.  A user wanting
the name of a file that s?he displays using a particular method (e.g.
command-line arg) to be added to the history is another thing.

Users should be able to specify the name-adding behavior they want.  Simply
adding the name of every file that gets displayed, no matter how, does not give
users the control they deserve.
