[PATCH] man: escape backslash in notmuch-tag example

[David Bremner]

The example was originally intended to have a literal backslash in it, but
'\ ' is interpreted by nroff as a non-breaking space.

It doesn't make much difference to the example, but the non-breaking
space triggers a bug in doclifter.
