as far as i can see it the XML output has similar issues:
space characters are not escaped and the filenames are
not defined as string attributes but just as plaintext
between tags.
afaik, most XML parsers collapse multiple spaces into a
single space.

when i look at the xml with an xml-viewer the SVN output
   <path
      action="A">/trunk/ a file with 2 spaces</path>
   </paths>
displays as
   <path action="A">/trunk/ a file with 2 spaces</path>

but i also tried it with the ruby-xml parser
and the parsed string was correct
   ( "/trunk/ a file with 2 spaces" )

i'm not sure what the xml standard defines
for multiple spaces in this case or how other xml
parsers handle this.

i noticed that other characters are escaped,
for example semicolons ';' are handled,
umlauts '' remain as utf-8.
   <path
      action="A">/trunk/a&amp;b-;2 3.txt</path>
   </paths>

but even IF i could use --xml for svn log,
there are several other commands
which fail in the same way:
  svn status -v
                 8 8 cat release-0.28.0 (from trunk6846)
                11 11 cat a file with spaces
                10 10 cat a&b-;2 3.txt
                12 12 administrator johnMyFile.c
                12 12 administrator johnMy spaced File.c

---
and these commands cannot output xml.
