    Fix an observed problem
    After rebuilding thus:
      $cd /opt/lmi/src/lmi
      $make eviscerate
      $rm -rf /opt/lmi/bin
      $logfile=log-`date -u +'%Y%m%dT%H%MZ'`; \
       echo "Log file is '$logfile.tar.xz'."; \
       ./install_msw.sh >$logfile 2>&1; \
       tar -cJf $logfile.tar.xz $logfile; mv ${logfile}* ..
      $git diff --no-index --color=always --color-moved=plain \
       ../log-20190519T1536Z ../log-20190519T2007Z \
       |sed -e's/^.\[3[12]m/&ZZZ/' |less -RS
    the resulting log was observed to contain:
      Error: Nonce directory '/opt/lmi/zzz/mingw-ad_hoc/ad_hoc' already \
      Probably it is left over from a previous failure.
      Just remove it unless you're sure you want whatever files
      it might contain.
      make: *** [install_mingw.make:114: initial_setup] Error 1
    Therefore, made evisceration more severe (the rebuild would have
    succeeded if '/opt/lmi/zzz' had been removed at the beginning)
    and automatic (in the particular case of rebuilding in the lmi
    source directory).
    Added '/opt/lmi/bin/' to the list of directories to be eviscerated.
    Do not store valuable files there, or twiddle their permissions so
    that 'rm --force' cannot remove them.
