+1, except don't just change this function but also all the other places we use
it: that's two other functions in io.c, and also:
subversion/libsvn_wc/entries.c:read_entries(),
subversion/libsvn_wc/log.c:run_log(),
subversion/svnlook/main.c:do_cat().
At a quick look, it seems right to change all of these to use a pool-allocated
buffer of SVN__STREAM_CHUNK_SIZE bytes.
