I might be wrong but I think any pathspec that begins with "-" needs to
be preceded by either a "--" marker or be specified as "./-filename",
else verify_filename just die. Therefore you would need to do something
like git reset ./- if you wanted to reset a file. I don't know if given
simply "-" as filename is desired since options starts with "-".
I don't know if you saw but Junio posted a while ago about about
allowing "-" as a stand-in everywhere a revision was allowed. He updated
a version on pu : "d40f108d"
