Bug fix for fontbanner(6)

[Greg Earle]

I have made the brazen assumption that if you merely specify a font name
for use via the -f option in fontbanner, it should go to the current font
directory (default DEFAULTDIR), and seek out that font.  The source as
distributed does not do this, because if you do not use the -d option,
it attempts to use the variable fontsdir inside the call to getoptions
(while it processes your switches) before 'fontsdir' has been set.  It
fails because it tries to look up the font name in /.  Here is a quick fix:

( Suitable for use with "patch -c" )
