[PATCH] emacs: wrap current search in parens when filtering

[Uli Scholler]

When filtering the current search further with notmuch-search-filter,
wrap the current search in parens.

This fixes unexpected behavior when the current search is
complex (like "(tag:this and date:one_week_ago..) or tag:that").
