*/ REBINT Text_Gob(void *richtext, REBSER *block)
/*
** Handles all commands for the TEXT dialect as specified
** in the system/dialects/text object.
**
** This function calls the REBOL_Dialect interpreter to
** parse the dialect and build and return the command number
** (the index offset in the text object above) and a block
** of arguments. (For now, just a REBOL block, but this could
** be changed to isolate it from changes in REBOL's internals).
**
** Each arg will be of the specified datatype (given in the
** dialect) or NONE when no argument of that type was given
** and this code must determine the proper default value.
**
** If the cmd result is zero, then it is either the end of
** the block, or an error has occurred. If the error value
** is non-zero, then it was an error.
