hm, interesting suggestion.   I don't know enough about mailcap to know
whether it makes more sense to adopt it directly or to use a
notmuch-specific configuration.

One difference: mailcap seems to be about displaying/editing data to the
user (including, for example, opening a graphical window to display a
JPEG), whereas we need to set up a mechanism to convert whatever kind of
document we get into plain text to feed it into xapian.  So we couldn't
fully piggy-back on the mailcap infrastructure, if i'm reading the
mailcap documentation correctly.  notmuch would need to use its own
mime-types file.

Anyone with more experience with this stuff (or stronger opinions) have
any insight on what approach makes more sense?

exactly :)
