It took a while to reproduce...

$ echo $'foo\nbar' | notmuch count --batch 
665
631

$ echo $'foo\n and bar' | notmuch count --batch
665
A Xapian exception occurred: Syntax: <expression> AND <expression>
Query string was:  and bar
0

Therefore: (wrong-type-argument number-or-marker-p A)

(I run non-byte-compiled version of (one-) notmuch.el and
got this as a backtrace:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p A)
  >(A 0)
  (or (plist-get options :show-empty-searches) (> message-count 0))
...
  (notmuch-remove-if-not
...
  notmuch-hello-query-counts
...

simpler way to reproduce:

$ notmuch count 'and bar'
A Xapian exception occurred: Syntax: <expression> AND <expression>
Query string was: and bar
0

Maybe the cli should be fixed ? (and/or make emacs MUA resilient to
this kind of result)
