Reading an MPS file fails if any tabs (ASCII 0x09) are used, even in a comment. This causes some MIPLIB files to fail reading.

A workaround is to use the --freemps option, even though the non-commented part of the file conforms to the stricter format.

This could be corrected by changing the routine read_card in file glplpx8a.c to ignore everything after a leading '*', similar to the way it is already done in read_char in the same file.
