TW-TS-005 reader: fix maximum line length bug TW-TS-005 section 4.1 states: The maximum allowed length of each line is 80 characters, not including the OS-specific newline encoding. The implementation of this line length limit in the TW-TS-005 hex file reader function in the present suite was wrong, such that lines of the full maximum length could not be read. Fix it. Note that this bug affects comment lines too, not just actual RTP payloads. Neither Annex A nor Annex B features an RTP payload format that goes to the maximum of 40 bytes, but if a comment line goes to the maximum allowed length of 80 characters not including the terminating newline, the bug will be triggered, necessitating the present fix.

/*
 * The function implemented in this module is an aid for AMR-EFR interworking:
 * it is meant to be invoked directly after amr_encode_frame(), it checks
 * the encoder output for MR122 DHF, and if the generated frame exactly
 * matches MR122 DHF, it is changed to GSM-EFR DHF.
