deleting invisible files in git

[Graham Percival]

input/lsr/spacing/
contains some .ly files with capitalized first letters.  (Page-*, 
Proportional-* )

Those were added by mistake; I've since added similar files with 
lowercase first letters (page-*, proportional-*).  However, I can't see 
the Upper Case .ly files in my git directory.  I've tried git reset 
--hard; still doesn't work.  Evidently git is intelligent enough to 
realize that the Capitalized files are duplicates of the lower-case 
(does it handle symlinks?), but now I can't get rid of them.

Cheers,
