Make svn log --search case-sensitive, because apr_fnmatch() doesn't perform
case-insensitive matching in a desireable manner -- it only case-folds ASCII
and can cause assertions on Windows when dealing with UTF-8 data.

See for discussion: http://svn.haxx.se/dev/archive-2013-04/0374.shtml

* subversion/svn/log-cmd.c
  (match_search_pattern): Don't use APR_FNM_CASE_BLIND.

* subversion/tests/cmdline/log_tests.py
  (log_search): Adjust test expectations accordingly.
