This will
a) Only work on Win NT and later (not Win9x) -- not that I care about
those platforms, and
b) APR already does that with file names on Windows, so it doesn't
always seem to help.
Anyway, this isn't the only kind of file name that won't work on
Windows; file names with colons or backslashes in them (which can be
created on Unix) will also break the Windows client.

Our position in similar situations in the past is that it's not
Subversion's job to support file names that the native OS can't handle.

We know that, but we also know that it would be a pretty pointless thing
to do, because other apps couldn't use such files.
