mailinfo: work around -Wstring-plus-int warning

Browse Source 
The just-released Apple Xcode 6.0.1 has -Wstring-plus-int enabled by
default which complains about pointer arithmetic applied to a string
literal:

    builtin/mailinfo.c:303:24: warning:
        adding 'long' to a string does not append to the string
            return !memcmp(SAMPLE + (cp - line), cp, strlen(SAMPLE) ...
                           ~~~~~~~^~~~~~~~~~~~~
