Folks,


executing

  mpost -progname=mpost -ini mf2pt1.mp \\dump

works just fine (with `mf2pt1.mp' in the current directory), while

  mpost -progname=mpost -ini /opt/lilypond/2.19.83/var/macports/build/_opt_lilypond_2.19.83_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_textproc_lilypond-devel/lilypond-devel/work/lilypond-2.19.83/mf/mf2pt1.mp \\dump

aborts with a segmentation fault.  This smells :-)  Is there a line
length limit for command line arguments?  Can this be increased with
an environment variable?
