AW: [PATCH]: Optimize merge_file_trivial()

Hi, Julian, [Re-Post, because I did forget to actually attach the patch...] Here's the second round. I hope I did catch all issues. As there were no comments about the names and the parameter order, I guess they're okay. The tests still look well: Summary of test results: 1619 tests PASSED 85 tests SKIPPED 38 tests XFAILED (1 WORK-IN-PROGRESS) [[ Optimize merge_file_trivial() by avoiding to read the files twice by using a new comparison function which compares 3 files at once. * subversion/include/svn_io.h (svn_io_filesizes_three_different_p): Add new declaration (svn_io_files_contents_three_same_p): Add new declaration * subversion/libsvn_subr/io.c (svn_io_filesizes_three_different_p): Add new function in analogy to svn_io_filesizes_different_p(). (contents_three_identical_p): Add new function in analogy to contents_identical_p(). (svn_io_files_contents_three_same_p): Add new function in analogy to svn_io_files_contents_same_p. * subversion/libsvn_wc/merge.c (merge_file_trivial): Use the new three-file comparison functions to avoid reading files twice.

I'll update the patch accordingly. Ah, I see. I've fixed those in r1349889. As for auto source formatting, I have settings for the Vim text editor, but I don't know about VS or a stand-alone tool. - Julian >> Please replace 'rsp' with 'and' or 'or' in the doc strings.
