"attr:whitespace=indent trail ..whatever other stuff.." is already a
non-starter.  In the example in the message you are responding to, I
want to find paths whose "whitespace" attribute is set to the exact
string "indent,trail,space".  And I do not want the pathspec magic
code to know how the interpretation of "whitespace" attribute treats
comma in the string.  It may or may not have any special meaning, so
if you meant "whitespace=indent trail ..whatever other stuff.."  to
mean "either whitespace is set to indent, or whitespace is set to
trail", then that is already unacceptable.
