You're saying that urxvt normally takes up 7 MB, and as soon as those
Unicode arrows are displayed it takes up 15 MB?  Weird.  Xfce terminal
here uses something like 37 MB at startup, and each new instance or new
tab costs somewhere between 0 and 200 KB.  (Closing tabs or instances
doesn't free any memory, it seems.)

Not 100.  Instead of 100%, ▲ should be shown.  Rounding shouldn't
happen -- percentages are "clipped": always rounded down.

Yes.  Because a bare number is too unclear: line number? kilobytes?
And to mimic the two bigger brothers.

There may be a difference, but Vim and Emacs and Gedit beep the
same for all cases.

*If* there will be a "silent" option, it will silence everything.
