Fixes formatting on some rare cases when a percent ends up
in the $CMD variable, like these below:
- When assigning a variable, $CMD ends up with the second parameter;
in this case, $CMD will contain '+%s%N', messing with the syntax:
$ a=`date +%s%N`
- A function (or command in general) that contains a percent symbol:
$ to\%() { echo $(( $1 * 100 / $3))\% } # $CMD=to%()
$ to% 2 of 10 # $CMD=to%
