-/*
- * Structure of the Haiku GUI code:
- *
- * There are 3 threads.
- * 1. The initial thread. In gui_mch_prepare() this gets to run the
- *    BApplication message loop. But before it starts doing that,
- *    it creates thread 2
- * 2. The main() thread. This thread is created in gui_mch_prepare()
- *    and its purpose in life is to call main(argc, argv) again.
- *    This thread is doing the bulk of the work.
- * 3. Sooner or later, a window is opened by the main() thread. This
- *    causes a second message loop to be created: the window thread.
- *
- * == alternatively ===
- *
- * #if RUN_BAPPLICATION_IN_NEW_THREAD...
- *
- * 1. The initial thread. In gui_mch_prepare() this gets to spawn
- *    thread 2. After doing that, it returns to main() to do the
- *    bulk of the work, being the main() thread.
- * 2. Runs the BApplication.
- * 3. The window thread, just like in the first case.
- *
- * This second alternative is cleaner from Vim's viewpoint. However,
- * the BeBook seems to assume everywhere that the BApplication *must*
- * run in the initial thread. So perhaps doing otherwise is very wrong.
- *
- * However, from a B_SINGLE_LAUNCH viewpoint, the first is better.
- * If Vim is marked "Single Launch" in its application resources,
- * and a file is dropped on the Vim icon, and another Vim is already
- * running, the file is passed on to the earlier Vim. This happens
- * in BApplication::Run(). So we want Vim to terminate if
- * BApplication::Run() terminates. (See the BeBook, on BApplication.
- * However, it seems that the second copy of Vim isn't even started
- * in this case... which is for the better since I wouldn't know how
- * to detect this case.)
- *
- * Communication between these threads occurs mostly by translating
- * BMessages that come in and posting an appropriate translation on
- * the VDCMP (Vim Direct Communication Message Port). Therefore the
- * actions required for keypresses and window resizes, etc, are mostly
- * performed in the main() thread.
- *
- * A notable exception to this is the Draw() event. The redrawing of
- * the window contents is performed asynchronously from the window
- * thread. To make this work correctly, a locking protocol is used when
- * any thread is accessing the essential variables that are used by
- * the window thread.
- *
- * This locking protocol consists of locking Vim's window. This is both
- * convenient and necessary.

+
+/*
+ * Structure of the Haiku GUI code:
+ *
+ * There are 3 threads.
+ * 1. The initial thread. In gui_mch_prepare() this gets to run the
+ *    BApplication message loop. But before it starts doing that,
+ *    it creates thread 2
+ * 2. The main() thread. This thread is created in gui_mch_prepare()
+ *    and its purpose in life is to call main(argc, argv) again.
+ *    This thread is doing the bulk of the work.
+ * 3. Sooner or later, a window is opened by the main() thread. This
+ *    causes a second message loop to be created: the window thread.
+ *
+ * == alternatively ===
+ *
+ * #if RUN_BAPPLICATION_IN_NEW_THREAD...
+ *
+ * 1. The initial thread. In gui_mch_prepare() this gets to spawn
+ *    thread 2. After doing that, it returns to main() to do the
+ *    bulk of the work, being the main() thread.
+ * 2. Runs the BApplication.
+ * 3. The window thread, just like in the first case.
+ *
+ * This second alternative is cleaner from Vim's viewpoint. However,
+ * the BeBook seems to assume everywhere that the BApplication *must*
+ * run in the initial thread. So perhaps doing otherwise is very wrong.
+ *
+ * However, from a B_SINGLE_LAUNCH viewpoint, the first is better.
+ * If Vim is marked "Single Launch" in its application resources,
+ * and a file is dropped on the Vim icon, and another Vim is already
+ * running, the file is passed on to the earlier Vim. This happens
+ * in BApplication::Run(). So we want Vim to terminate if
+ * BApplication::Run() terminates. (See the BeBook, on BApplication.
+ * However, it seems that the second copy of Vim isn't even started
+ * in this case... which is for the better since I wouldn't know how
+ * to detect this case.)
+ *
+ * Communication between these threads occurs mostly by translating
+ * BMessages that come in and posting an appropriate translation on
+ * the VDCMP (Vim Direct Communication Message Port). Therefore the
+ * actions required for keypresses and window resizes, etc, are mostly
+ * performed in the main() thread.
+ *
+ * A notable exception to this is the Draw() event. The redrawing of
+ * the window contents is performed asynchronously from the window
+ * thread. To make this work correctly, a locking protocol is used when
+ * any thread is accessing the essential variables that are used by
+ * the window thread.
+ *
+ * This locking protocol consists of locking Vim's window. This is both
+ * convenient and necessary.
