In the patch I reviewed, there was a

+ cmd = [ self.__svn_path, "youngest", self.__repospath ]

call a few lines above. I left it in the quoted context of my review.
I guess you mean you fixed that issue in the new iteration of the patch.

Indicating that further argv arguments are paths or URLs and not
options, even if they begin with '-'. (Note that we set
os->interleave=1 in sub_main().)

No, I worry about the Python language defining a meaning to the escape


inside a double-quoted string, just like it already defines


to be a newline character (and not literal backslash followed by literal
small letter N).


Thanks for the fixes.
