The addition of mml-quote-region (notmuch-mua.el) in 2c6710e3 breaks
automatic signing in replies. When replies are mml-quoted and signing
is enabled by default the "<#part sign=pgpmime>" string will appear on
line 1. This will be consumed during the application of the
mml-quote-region function and transform into the inert string
"<#!part sign=pgpmime>". The result is that responses will no longer
be signed by default.

This fix moves the point forward one line before applying the quoting
function.

Consideration: Clients not signing mail by default. The first line of
their responses would be skipped when the quoting function is
applied. This string takes this general form:

Because the string is generated by notmuch I don't believe this fix
introduces the possibility for malicious mml commands being omitted
from the quoting.
