int mtext_del (MText * mt, int from, int to)
Delete characters in the specified range destructively. The mtext_del() function deletes the characters in the range from (inclusive) and to (exclusive) from M-text mt destructively. As a result, the length of mt shrinks by (to - from) characters.
If the operation was successful, mtext_del() returns 0. Otherwise, it returns -1 and assigns an error code to the external variable merror_code.
