Description

Issue was discussed in user mailing list with the result that this seems to be 
worth an issue.

In short, if you consider svn:externals as a kind of embedded checkout, it 
should behave like a regular checkout and accept the same parameters.

Example:
svn co -rHEAD path@peg =>
- checks out HEAD if path still exists on HEAD _and_ a continuous backward 
history from HEAD to peg does exist as well
- otherwise: Subversion reports an error (this is in what I am interested in in 
my use-case)

This is the right and expected bevaviour according to the svn book.

Please enhance svn:externals's syntax to accept HEAD as operative revision and 
let it work similar to a regular svn checkout.

A simple on-the-fly replacement of -rHEAD by -r{revision of HEAD} on each access 
should do the job, I guess.
