[Message part 1 (text/plain, inline)]

I am on Debian with a case sensitve file system. I have a directory
named "~/media/SANSA CLIPP". After starting emacs -Q and setting the
option Read File Name Completion Ignore Case to t,
I type C-x d ~/media/sa then press the Tab key. Emacs completes the
file name to ~/media/saNSA CLIPP/ which does not exist. In previous
versions of emacs the "sa" would have been corrected to "SA".
