[PATCH v2] lib: Fix name reordering to handle commas without spaces

[Adam Wolfe Gordon <awg+notmuch@xvx.ca>]

Notmuch automatically re-orders names of the format "Last, First" to
"First Last" when the associated email address is
First.Last@example.com. But, if a name is of the format "Last,First"
then notmuch will format the name as "irst Last". Handle any number of
spaces after the comma, including none.

Good idea, Tomi. This version handles any number of spaces.
