-Because eximstats arguments are often passed as variables,
-we can't rely on shell parsing to deal with quotes. This
-subroutine returns $ARGV[1] and does a shift. If $ARGV[1]
-starts with a quote (' or "), and doesn't end in one, then
-we append the next argument to it and shift again. We repeat
-until we've got all of the argument.
-
-This isn't perfect as all white space gets reduced to one space,
-but it's as good as we can get! If it's esential that spacing
-be preserved precisely, then you get that by not using shell
-variables.
