Oh, I was afraid it might be deprecated, I had tried mintty in the
last few weeks, but was unable to get 'WordChars' setting to work
as well as rxvt's cutchars.

I launch rxvt with a shell script using:

  font_sz=${1:-17}

  cutchars=$'\140'$'\042'$'\047''+-&()*,;<=>?@[]{|}/.:'
    # \140 == `
    # \042 == "
    # \047 == '

    # "Rxvt*cutchars" in ~/.Xdefaults ( usually a link to /etc/skel/.Xdefaults )
    #    but stopped working for me, 1st noticed not working in 2012 or 2011

  exec rxvt \
    -cutchars  $cutchars \
    -backspacekey $'\010' -geometry 100x33 \
    +rv \
    -bg black \
    -fg white \
    -fn "Lucida Console-$font_sz"  \
    -sr -sl 5000 \
    -e /bin/bash --login

I've been unable to get the equivalent of cutchars to work in mintty.
Putty was good at that, but I stopped using putty because of the 'procps' hangs.
