Well "svn revert" is one of the basic SVN commands (that I personally
use far more often than "patch -R", but YMMV). We're not talking about
some advanced use of Mercurial queues. The point is a bit subtler here
though: if you use "patch -R" after you have done some changes of your
own, the checkout will not be restored to its pristine state, which
may bite you later. "svn revert -R ." ensures everything is clean.

Arguably, even "patch" isn't familiar to Windows developers. It doesn't
come bundled and has to be installed separately, and I've seen some
people use the TortoiseSVN GUI for applying patches.
