Glpk output routines keep original names of rows and columns, if it is
possible. It it is not possible (for example, fixed mps format allows
names not longer than 8 characters), fake names are used, like x[123] in
cplex format or C0000123 in fixed mps format. In this sense only free
mps format is reliable.
