Yes, some shells require you to escape the curly braces.
I was hoping at this point to refer you to the page in the book where this is
explained, but it appears not to be explained there.
http://svnbook.red-bean.com/nightly/en/svn.tour.revs.specifiers.html#svn.tour.revs.dates
Perhaps you could submit feedback to the authors of the book and ask them to
include this information? They have their own mailing list.
