Hmph.  This is mostly useful not to error out when user (perhaps
mistakenly) expects that the end of file is spelled as "$"; both
"git blame -L<begin>" and "git blame L<begin>," have always meant
"til the end", IIRC.

Because I do not offhand think of other & better uses of "$" as a
special case that conflicts with "the end of file", I do not think
it is a bad patch that needs to be rejected, though.
