verify: always check rawsize

Previously, verify only checks "rawsize == len(rawtext)", if
"len(fl.read()) != fl.size()".

With flag processor, "len(fl.read()) != fl.size()" does not necessarily mean
"rawsize == len(rawtext)". So we may miss a useful check.

This patch removes the "if len(fl.read()) != fl.size()" condition so the
rawsize check is always performed.

With the condition removed, "fl.read(n)" looks unnecessary so a comment was
added to explain the side effect is wanted.
