Yes, I agree that the "Ignore case changes" is pretty useless as it is.
That option should behave as "diff -i" does:

$ head -5 /usr/share/dict/words
A
a
aa
aal
aalii
$ sed s/ignore/highlight /usr/share/dict/words | tr '[a-z]' '[A-Z]' > /tmp/WORDS
$ head -5 /tmp/WORDS
A
A
AA
AAL
AALII
$ diff -i /usr/share/dict/words /tmp/WORDS

Now if I run TortoiseMerge with "Ignore case changes" checked in single-pane
view, I get:
  1 A
  2 a
  2 A
  3 aa
  3 AA
  4 aal
  4 AAL
  5 aalii
  5 AALII
etc...
The "previous difference" and "next difference" buttons stop on every
line, and there are so many lines in the file that I don't see any
colored bars at the very left that indicate where the changed lines
are. This does not help me locate the real differences at all, whereas
diff -i immediately shows the changes I'm interested in.
Please change the "Ignore case changes" to do a case-insensitive
comparison of the files.
