How to add files to Subversion containing “@” in their names

This doesn’t work:
$ svn add icon@2x.png
svn: warning: 'icon' not found
This does:
$ svn add icon@2x.png@
A (bin) icon@2x.png
You must append another at-sign (“@”) to any filename that contains one that isn’t intended to be interpreted as a revision specifier.
I suspect this has been a first-time issue for a lot of Subversion users this week.
