RFR (S) 8049300: jjs scripting: need way to quote $EXEC command arguments to protect spaces

[Hannes Wallnoefer]

If the command ends with '\' the last token will be lost, you need to 
check toAppend after the loop.

Looks good apart from that.

The implementation of the $EXEC command would tokenise using a plain StringTokenizer, which splits a string at space characters regardless of quoting. The new implementation employs a StreamTokenizer and some extra logic to handle escaped spaces.
