Ah, OK, makes sense. Note that I have not used 'pathspec magic' or the attribute system in git (never felt/had the need)! ;-)
So, at risk of annoying you, let me continue in my ignorance a little longer and ask: even if you have to protect all of this 'magic' from the shell with '/" quoting, could you not use (nested) quotes to protect the <value> part of an <attr>? For example:
git ls-files ':(attr:whitespace="indent,trail,space",icase)'
[Hmm, I don't seem to be able to find documentation on the syntax of these features (apart from the code, of course).]
