From RFC822, August 13, 1982, page 5:

    ... can be split into a multiple line representation; this
    is called "folding". The general rule is that wherever there
    may be linear-white-space (NOT simple LWSP-chars), a CRLF
    immediately followed by AT LEAST one LWSP-char may instead
    be inserted.

In other words, it doesn't have to indented with a TAB.
