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.

rebase: rename "target" to "destination" in messages The help text for rebase calls it "the destination" (never "target"), so let's use that in messages as well.
