Up to now, this issue stayed undetected simply for the fact that we
core developers do not use or even know the correct behavior of "Caps
Lock". So triggered by your message, I browsed to Wikipedia and
discovered that we're in good company being uncertain of the correct
caps-lock behavior

Nevertheless, it's possible to change the character-generator mapping
for caps-lock rendering differently from the shift keys by applying
the caps-lock ROM to a different modifier (e.g., mod4). Then, you have
to provide the character mapping in the <map mod4="yes"> node of the
en_us.chargen file.

This is a known issue originating from the bash port, which does not
adapt to the terminal capabilities like, for example, ViM.
