Bug: problem decoding some non-ascii characters in subjects

[Albin Stjerna]

Hi,

I've been noticing that notmuch has some problems decoding certain strangely-encoded non-ascii characters in certain emails. For example, today I got this: [BIBLIST] Digitaliseringensprojektens skadliga f=?ISO-8859-1?Q?=F6rk=E4rlek_f=F6r_?= PDF-formatet (should be rendered: »Digitaliseringsprojektens skadliga förkärlek för PDF-formatet«).

Apparently, some metadata is passed on to help the MUA decode the string, but notmuch doesn't seem to handle it. Entire emails can of course be supplied as needed.
