wish: notmuch-emacs: provide completion in notmuch-search for path: as for tag:

[Gregor Zattler]

Dear notmuch developers,

when used interactively notmuch-search provides completion for
tag: (and is:) but not for e.g. path: (and folder:) prefixes.

For obvious reasons it would be very convenient if directory/file name
completion were available especially for users who still filter
their emails in different folders.

Other candidates for completion are mimetype: id: and perhaps attachment:.


Thanks for developing notmuch and your attention, Gregor
