Thank you for the hint. I found the thread, and after reading it I notice that the opposition is based on that restoring the position doesn't put the window on the desired monitor. I can't test this right now. I've rewritten the commit message as follows. Whether or not the position should be restored seems to be a personal preference, and the patch applies my and your preference, but obviously not everyone's. Please let me know whether I understood the situation correctly or not.

    Revert "gitk: Only restore window size from ~/.gitk, not position"
    
    This reverts commit b9bee11526ec (gitk: Only restore window size from
    ~/.gitk, not position, 2008-03-10).
    
    The earlier commit e9937d2a03a4 (Make gitk work reasonably well on
    Cygwin, 2007-02-01) reworked the window layout considerably. Much of
    this became irrelevant around 2011 after Cygwin gained an X11 server
    and switched to a supportable port of the Unix/X11 Tcl/Tk (it is now
    on the current 8.6 code base).
    
    Part of the necessary change was to restore the window size across
    sessions, but the position was also restored. This raised complaints
    on the mailing list[*], because Gitk was opened on the wrong monitor.
    b9bee11526ec was the compromise, because it was only the size that
    mattered for the Cygwin layout engine to work.
    
    I personally, find it annoying when Gitk pops up on a random location
    on the screen, in particular, since many other applications restore
    the window positions across sessions, so why not Gitk as well? (I do
    not operate multi-monitor setups, so I cannot test the case.)
