1. Why white space is the only delimiter in jam?
It was a _mistake_. At the time ('93) whitespace in file names
was very uncommon, but one platform critical to us was VMS.
You know, $sys$device:[user.jam]parse.c;3 VMS.
I still think sparse quoting makes Jamfiles easy to read, but
requiring whitespace around the ; is very error prone.
If there is a compatible way of changing this without a "mode
bit," I'm all ears.
