I was intending to add the port to the 1.4 branch too, but after doing svn merge, svn diff does not show the new 100h subdir and its content. While this might be correct behaviour (I don't know), I decided not to go ahead.
Thanks for doing this port
I merged it over in 1.4 rev 4636.
I think what you saw is normal, when a merge adds a directory, only the top level directory is added. The contained files are unmodified. Some older versions of svn might have behaved differently.
