'stating for the full name first' will need to work for URLs as well,
possibly a round trip to the server? Having different behaviour for
working copy paths and URLs would seem to be a bad idea.
Since there are already standard files on my system that include a
single '@' in the name I feel we should use a different delimiter. If
we choose something as common as '@' we definitely need a way to allow
filenames containing the delimiter. Perhaps some sort of escape
sequence or perhaps simply a trailing delimiter e.g. assuming an '@'
delimiter the filename 'foo@123@' could be passed as 'foo@123@@'
representing a filename with no revision.
Perhaps all we need to do is to assume that given a filename foo@bar,
then if bar fails to parse as a revision then rather than returning
SVN_ERR_CL_ARG_PARSING_ERROR assume that the entire foo@bar is the
filename. This would certainly cover all the existing cases on my
system, but it might involve too much 'magic' to be sensible. Just as
working copy paths and URLs should have consistent behaviour I feel
the filenames 'fr_FR@euro' and 'fr_FR@head' should behave the same
