Add limit and offset to notmuch show

[Jörg Volbers]

Hi,

I'd like to repeat my wish to add some kind of search limit to 
notmuch show, like it is already implemented in notmuch search. 
Reason being that I written have my own little elisp client which 
allows me to browse through "tagsets", that is, I look at all 
mails corresponding to some predefined sets of tags. On the left 
the tagset, on the right a preview of the matching threads. Since 
it is only a preview, it simply makes no sense to execute all of 
the query, so it would be great if I could simply pass some limits 
to the query.

I believe my use case is not rare. A combination like the 
parameters offset/limit already used by notmuch-search would allow 
to considerably speed up all kind of client operations. The client 
could just act on smaller parts or impose sensible limits. For 
example, if looking at all mails, it makes sense to only show the 
first 500 or so and only load further mails on request.

Regards,
Jörg
