Re: Can't checkout svn:externals URL using Peg revision

Actually, I think he needs *both* -r and peg-rev, and I can see a
valid reason why you need peg-revs in externals (and, btw, so far as
I can see these are not currently supported).

While you are correct that he needs a -r20 switch in the external to
make sure he always gets the same rev of the file, he also needs a
peg-rev. Otherwise, a rename operation could break the external. For
example, renaming "Common" to "Common2" would break the external,
since "Common" no longer exists in HEAD.
