After looking at collects/syntax-color/scheme-lexer.ss, I realized all
the reader syntaxes I mentioned above are what the "Other" color is
for! :)  To make the coloring just the way I wanted it (I don't know if
this affects the semantics of how DrScheme interprets the source
code...), I made the Other color the same as Parenthesis color and made
this small change:
