rsync - Jan 2014 - --ignore-case option does not ignore pathname case?

tested with 3.07 and 3.1 with --ignore-case patch applied

cd /tmp
mkdir -p a/b/c/d/e/f
mkdir -p A/b/C/D/e/F
add some files to a/b/c/d/e/f/
rsync -r --ignore-case a/ A/
>> creates b/c/d/e/f/<files>
Why is it not ignoring case?  I expect it to add all files in 'f' to
'F'

Because you're not running it on a case-ignoring filesystem.  That patch is
(sadly) only a partially effective set of changes that helps rsync to deal
with a filesystem that doesn't differentiate upper-/lower-case when naming
files.  Rsync's main algorithm of probing for files by name (via stat)
didn't change, and thus it doesn't try to find an alternate name for the
same file if the filesystem isn't conglomerating them together (and indeed,
it totally fails to notice if the case on a filename has changed on the
server compared to the file's name on the receiver).

For a means of fixing this, I'm imaging having the code that is used for
--delete-during getting modified to notice changes in case and trying to
fix them (even if rsync isn't doing a delete-during run).  If that were
done, the patch would probably then be in good enough shape to finally be
included in the main code.
