should confirm post on truncate

[jeremy-w]

Currently, wry post truncates without warning when the post content is too long.

Instead, it could do something like this:

% wry post 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef out of space already?
Warning: Post exceeds 256-character limit by 21 characters.

Post would include:

    123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 
    123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 
    123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 
    123456789abcdef 123456789abcdef 123456789abcdef 123456789abcdef 

Post would omit 21 characters:

    out of space already?

Post anyway? (y/n)

Implement as three modes with default and flag:

• Truncate without warning
• Truncate with warning (as seen in previous comment)
• Split into multiple posts
