Flags are returned with leading backslash but are set without?

[mikemee]

When I get flags from a fetch, they come back as:

flags:["\\Seen"]

However when using append and passing flags, they have to be sent as:

flags:["Seen"]

Will you accept a pull request that allows append to accept the same options.flags as retrieved from fetch? (Most likely by checking each flag for a leading backslash and not adding it if its not already there).

I would probably accept something like that.

Since the rewrite in master, I'm leaning more towards keeping the backslash everywhere.

@mscdex close?
