easy install: two rc file update bugs fixed

Browse source 
The "msysgit doesnt have 'comm'" commit (from 2 days ago), had 2 bugs:

  - (smaller) the "+++" which was part of the diff header was triggering
    a spurious rc file "new variables" warning, but there were no actual
    variables to update
  - (bigger) worse, the grep command, when there were no matches,
    coupled with the "set -e" to kill the program right there (ouch!)
