-/* An fstream can be in at most one of put mode, get mode, or putback mode.
-   Putback mode is a variant of get mode.
-
-   In a filebuf, there is only one current position, instead of two
-   separate get and put pointers.  In get mode, the current position
-   is that of gptr(); in put mode that of pptr().
-
-   The position in the buffer that corresponds to the position
-   in external file system is normally _IO_read_end, except in putback
-   mode, when it is _IO_save_end.
-   If the field _fb._offset is >= 0, it gives the offset in
-   the file as a whole corresponding to eGptr(). (?)
-
-   PUT MODE:
-   If a filebuf is in put mode, then all of _IO_read_ptr, _IO_read_end,
-   and _IO_read_base are equal to each other.  These are usually equal
-   to _IO_buf_base, though not necessarily if we have switched from
-   get mode to put mode.  (The reason is to maintain the invariant
-   that _IO_read_end corresponds to the external file position.)
-   _IO_write_base is non-NULL and usually equal to _IO_base_base.
-   We also have _IO_write_end == _IO_buf_end, but only in fully buffered mode.
-   The un-flushed character are those between _IO_write_base and _IO_write_ptr.
-
-   GET MODE:
-   If a filebuf is in get or putback mode, eback() != egptr().
-   In get mode, the unread characters are between gptr() and egptr().
-   The OS file position corresponds to that of egptr().
-
-   PUTBACK MODE:
-   Putback mode is used to remember "excess" characters that have
-   been sputbackc'd in a separate putback buffer.
-   In putback mode, the get buffer points to the special putback buffer.
-   The unread characters are the characters between gptr() and egptr()
-   in the putback buffer, as well as the area between save_gptr()
-   and save_egptr(), which point into the original reserve buffer.
-   (The pointers save_gptr() and save_egptr() are the values
-   of gptr() and egptr() at the time putback mode was entered.)
-   The OS position corresponds to that of save_egptr().
-
-   LINE BUFFERED OUTPUT:
-   During line buffered output, _IO_write_base==base() && epptr()==base().
-   However, ptr() may be anywhere between base() and ebuf().
-   This forces a call to filebuf::overflow(int C) on every put.
-   If there is more space in the buffer, and C is not a '\n',
-   then C is inserted, and pptr() incremented.
-
-   UNBUFFERED STREAMS:
-   If a filebuf is unbuffered(), the _shortbuf[1] is used as the buffer.

-/* THE JUMPTABLE FUNCTIONS.
-
- * The _IO_FILE type is used to implement the FILE type in GNU libc,
- * as well as the streambuf class in GNU iostreams for C++.
- * These are all the same, just used differently.
- * An _IO_FILE (or FILE) object is allows followed by a pointer to
- * a jump table (of pointers to functions).  The pointer is accessed
- * with the _IO_JUMPS macro.  The jump table has a eccentric format,
- * so as to be compatible with the layout of a C++ virtual function table.
- * (as implemented by g++).  When a pointer to a streambuf object is
- * coerced to an (_IO_FILE*), then _IO_JUMPS on the result just
- * happens to point to the virtual function table of the streambuf.
- * Thus the _IO_JUMPS function table used for C stdio/libio does
- * double duty as the virtual function table for C++ streambuf.
- *
- * The entries in the _IO_JUMPS function table (and hence also the
- * virtual functions of a streambuf) are described below.
- * The first parameter of each function entry is the _IO_FILE/streambuf
- * object being acted on (i.e. the 'this' parameter).
