+<h3> OPTION SYNTAX</h3>
+<pre>
+ All options accepting an argument can be used with '=' or ':' as a sep‐
+ arator. Except for boolean options (which would be ambiguous), a space
+ can also be used as a separator. The following are all equivalent:
+
+ notmuch --config=alt-config config get user.name
+ notmuch --config:alt-config config get user.name
+ notmuch --config alt-config config get user.name
