I did not review the code, but here is a general comment for both
patches (but especially for the first one).  It would be nice to have a
more detailed documentation for hooks.  Docstring like "Enable Visual
Line mode." for a function named `notmuch-show-turn-on-visual-line-mode'
is near useless.  It is quite obvious that the function enables
visual-line-mode from it's name.  And it does not give any information
on why would someone actually want to use it.  I do not remember what
visual-line-mode is exactly, so to understand whether this hook is
actually useful for me, I have to read visual-line-mode docs, think
about how it helps in notmuch-show, read some code, perhaps, etc.  I
would argue that since the hook itself is trivial, the main point in
having it is to provide a clearly documented solution for a common
problem for those who do not know how to solve this problem right away.
Currently, those who know what visual-line-mode is do not need this
hook, because they can easily write their own, and those who do not know
what visual-line-mode is can not use this hook, because it says nothing
about why it is actually useful.

Also, in addition to better docs, I would rename
`notmuch-show-turn-on-visual-line-mode' to something that reflects what
it does from user POV (like the other two hooks).

Though, the fact that the hook is enabled by default makes the above
arguments less important, I guess.

Regards,
  Dmitry
