-rv on a tty

-rv on a tty

[Eli Zaretskii]

Bug #5421 is a regression from Emacs 22, so I think it should be fixed
before releasing v23.3.

(This got even worse on the trunk, where -fg and -bg switches seem to
produce no effect on the initial frame, only on additional frames.
The -rv switch doesn't affect even the additional frames.)

I tried to figure this out, but failed to find the culprit before I
ran out of time.  It looks that we ought to DTRT, since we call
tty-handle-reverse-video in frame-notice-user-settings (which in turn
is called from startup.el after all the command-line switches were
processed), but for some reason that call doesn't have the effect on
the display, although the frame parameters are modified as expected.

Any ideas?

I'll take a look at it if I find the time, but I do with the -rv option
had never been invented.  It seems to serve no purpose except make
redisplay more complicated.

Thanks.

I agree that it complicates things, but I think we didn't invent it:
it's a standard option of every GUI application on X, isn't it?

It was standard on Xt-based applications, but not so for Gtk+ or Qt-based applications.

Switching foreground and background was easy back then with old style fonts.  With aa-fonts and transparency things are more complicated.
