``--body=(true|false)``
If true (the default) **notmuch show** includes the bodies of the
messages in the output; if false, bodies are omitted.
- ``--body=false`` is only implemented for the json and sexp formats
- and it is incompatible with ``--part > 0.``
+ ``--body=false`` is only implemented for the text, json and sexp
+ formats and it is incompatible with ``--part > 0.``
This is useful if the caller only needs the headers as body-less
output is much faster and substantially smaller.
