So why not > fix it? Are you sure that "whitespace" of syntax has the same meaning as the "whitespace" of show-trailing-whitespace? For instance, currently ^L (formfeed) has syntax "whitespace". But, it is displayed with glyph "^L". Should it be the target of show-trailing-whitespace? For instance, currently NBSP (U+00A0) has syntax "." (punctuation), and it is displayed with special face to indicated the existing of that character. Should it be changed to "whitespace" syntax, or shoudn't be changed? Have you considered these things? Please try M-x apropos RET whitespace RET. The word "whitespace" is used in slightly different meanings. I thinks we can't blindly use "whitespace" syntax in some cases. --- Kenichi Handa handa@m17n.org
