MakeBufClip (hbuf, fClip)
If fClip is True, this turns the file buffer hbuf into a Clip buffer. Following this, the buffer will appear as a regular clip in the Clip Window.
If fClip is False, this turns the buffer into a regular, non-clip file buffer.
Clip buffers are automatically saved to the Clips subdirectory of the Source Insight program directory when Source Insight exits.
