12  * Implements client side of org.netbeans.modules.emacs editor
13  * integration protocol.  Be careful!  The protocol uses offsets
14  * which are *between* characters, whereas vim uses line number
15  * and column number which are *on* characters.
16  * See ":help netbeans-protocol" for explanation.
17  *
18  * The Netbeans messages are received and queued in the gui event loop, or in
19  * the select loop when Vim runs in a terminal. These messages are processed
20  * by netbeans_parse_messages() which is invoked in the idle loop when Vim is
21  * waiting for user input. The function netbeans_parse_messages() is also
22  * called from the ":sleep" command, to allow the execution of test cases that
23  * may not invoke the idle loop.
