We discussed this on IRC.  And, surprisingly, everyone agreed on
changing the default to a space in a separate patch.

But my other comment for this patch is still relevant: please rename
`notmuch-thousands-separator' to `notmuch-hello-thousands-separator'.

If you decide to make another patch that changes the default to a space,
please add this link [1] to the preamble and a citation:

  Therefore the space is recommended in the SI/ISO 31-0 standard,
  and the International Bureau of Weights and Measures states that "for
  numbers with many digits the digits may be divided into groups of
  three by a thin space, in order to facilitate reading. Neither dots
  nor commas are inserted in the spaces between groups of three".

Regards,
  Dmitry
