char-displayable-p and jisx0208

[Jesper Harder]

`char-displayable-p' returns nil for Japanese jisx0208 characters
even though they are displayable for me:

  (char-displayable-p ?元) ==> nil

It seems to happen because `x-list-fonts' is called with the pattern
"-*-*-jisx0208.1990".

On my system all appropriate fonts end in "jisx0208.1990-0".  The
character above is displayed with

  -Shinonome-Gothic-Medium-R-Normal--12-110-75-75-C-120-JISX0208.1990-0
