------------------------+---------------------------------------------------
 With Cbc 2.0, reading in an .lp.gz file with first line being a comment
 line (starting with a '\') gives the following error:

 Coin:import enlight4.lp.gz
 At line 1 \This file was automatically generated by Zimpl
 Unknown image \This file was automatically generated by Zimpl at line 1 of
 file ./IP/enlight/enlight4.lp.gz
 Consider the possibility of a compressed file which zlib is unable to read
 Coin0008I  read with -2 errors
 There were -2 errors on input

 The instance 'enlight4.lp.gz' can be found in the contributed section of
 the MIPLIB2003 web site.
