emacs: Don't regard a manually indented '>' as introducing a citation.

In the message mentioned in the previous commit, an ASCII diagram was
included in which '>' was used as the first non-whitespace character
in a line. Notmuch previously (and mistakenly) regarded this as a
citation.

We fix this by only regarding a '>' in the first column of an email as
introducing a citation.
