Hi Bob,

Thanks for the tip about the ulem package. What I was looking for was a 
way to set options for the hyperref package, such that


colors, underlines, wraps if required, and makes a working hyperlink of 
"different", without having to specify \underline, \uline or \cuuline 
explicitly. Also, I was looking for a solution that works for \url too, 
namely for:


coloring, underlining, wrapping if required, and making a working 
hyperlink of "http://www.apple.com".

Finally it seems that the ulem package can be used for patching the 
commands of hyperref.sty; this surprises me slightly given the 
relatively low-level of these commands. What seems to work (stripping 
out all unnecessary packages and options):


% Now we redefine certain commands of hyperref.sty
% The following for \url
\def\url@#1{\hyper at linkurl{\uline{\Hurl{#1}}}{#1}}
% The following for \href
\def\hyper at link@[#1]#2#3#4{%
   \protected at edef\Hy at tempa{#2}%
   \ifx\Hy at tempa\@empty
     \hyper at link{#1}{#3}{\uline{#4}}%
     \expandafter\hyper at readexternallink#2\\{#1}{#3}{\uline{#4}}%
