Thanks for the script.sh, I understand now. For your script, subversion
COULD in theory return what you are looking for: the contents of file2_at_4,
but the current algorithm can't (it's explained in the peg rev section of
the book).
But, things get complicated very easily. If you then do:
$ svn cp file://$repos/file1_at_1 file3
$ svn ci -m 'Commit 5'
Now what answer would you expect when you run:
$ svn cat -rHEAD file://$repos/file1_at_1
Both file2_at_5 and file3_at_5, have lines of history back to file1_at_1. You just
can't pick one of the two and show that, although I suppose you could
display both, but I rather not think about trying to support that. :)
Hope that helps.
