Dear all,

when I load an mpeg2 ts file, I always get an error pop up saying the last
packet is incomplete, even when the file has N*188 bytes.

For N*188 bytes, mp2t_read_data() is called N+1 times, reading 0 bytes the last
time. It then sets *err=WTAP_ERR_SHORT_READ. I understand that getting 0 bytes
is not a short read but the end of file. If I ask for 188 bytes and get
0<x<188, it's a short read.

The attached patch corrects this.

You can use the files attached to #6908 to test it. The 8.xxPackets... should
bring up the error popup, the others shouldn't.

Best regards,

   Martin
