1) An unquoted space is always a separator, even when not "in_arg".
2) When a new destination buffer must be allocated during variable
substitution, only copy data from the active buffer to the new
one when we *are* "in_arg".
These were noticed when testing variable-substitution of variables
which have null values, and are not inside quoted strings...

happen in #-lines, but we might as well get it right. Also fix it so
that "" and "" will create a zero-length argument.

used to provide all the flexibility (and more!) that was lost by recent
changes to how the kernel parses #!-lines in shell scripts.
The '-P' option provides a way to specify an alternate set of directories
to use when searching for the 'utility' program to run. This way you can
be sure what directories are used for that search, without changing the
value of PATH that the user has set. Note that on FreeBSD 6.0, this
option is worthless unless the '-S' option is also used.

it cannot be a request to set the value of a valid environment variable.

to tack two NULs onto buffers. With the new, soon to come, parsing code
this isn't the case anymore in all cases, so fix this.

shell was the ksh. This failed if the default shell was sh or csh and
the user switched to ksh.
