I.... think you were better off with -r20 rather than @20.

I don't think externals support peg revision notation, nor do I see a
reason why they should.

"svn://server/repos/Common_at_20" means "find the object that was called
svn://server/repos/Common in revision 20 of the repository, and get
its contents from -rHEAD". This is not what you want if you're trying
to protect against upcoming changes to Common.

"-r20 svn://server/repos/Common" means "find the object called svn://
server/repos/Common in the HEAD revision of the repository, and get
its contents from -r20". This is what you want.
