windows: replace single quote with double quote when translating to cmd.exe

Since cmd.exe doesn't understand single quotes, single quotes to prevent $var
expansion is basically unusable without this.  Single quote isn't allowed in a
path name, so it seems unlikely to come up otherwise.

#!/usr/bin/env python
#
# A portable replacement for 'seq'
#
# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP
