send-email: recognize absolute path on Windows

On Windows, absolute paths might start with a DOS drive prefix, which these two checks failed to recognize. Unfortunately, we cannot simply use the file_name_is_absolute helper in File::Spec::Functions, because Git for Windows has an MSYS-based Perl, where this helper doesn't grok DOS drive-prefixes. So let's manually check for these in that case, and fall back to the File::Spec-helper on other platforms (e.g Win32 with native Perl) Signed-off-by: Erik Faye-Lund <kusmabite@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
