[PATCH 2/3] send-email: drop misleading function prototype

[Junio C Hamano <gitster@pobox.com>]

From: Ramkumar Ramachandra <artagnon@gmail.com>

The subroutine check_file_rev_conflict() is called from two places,
both of which expects to pass a single scaler variable and see if
that can be interpreted as a pathname or a revision name.  It is
defined with a function prototype ($) to force a scaler context
while evaluating the arguments at the calling site but it does not
help the current calling sites.  The only effect it has is to hurt
future calling sites that may want to build an argument list in an
array variable and call it as check_file_rev_confict(@args).

Drop the misleading prototype, as Perlcritic suggests.
