#1079: Fix parsing of encoded words.
This is a behavior change: before this leading and trailing spaces were
stripped from ASCII parts, now they are preserved. Without this fix we didn't
parse the examples in the RFC correctly, so I think breaking backward
compatibility here is justified.
Patch by Ralf Schlatterbeck.
