This adds the --ignore-case option, which makes rsync compare filenames
in a case-insensitive manner.
+To use this patch, run these commands for a successful build:
+
+ patch -p1 <patches/ignore-case.diff
+ ./configure (optional if already run)
+ make
+
+TODO:
+
+ - Make this code handle multibyte character encodings, and honor the
+ --iconv setting when converting case.
