allow secondary/fallback fonts to provide real glyphs at those codepoints.

The @code{TamzenForPowerline} fonts provide additional @code{Powerline} symbols,
which are programatically injected with @code{bitmap-font-patcher} and
later hand-tweaked with the gbdfed(1) editor:

@enumerate
@item all icons are expanded to occupy the maximum available space
@item the branch of the fork icon ( U+E0A0) was made larger than the trunk
@item for the newline icon ( U+E0A1), the @emph{N} was made larger at the bottom
@item the keyhole in the padlock icon ( U+E0A2) was replaced with @emph{//} lines.
