1bc2296bac Double NARGS
I just ran a simple one-liner[1] to find the average filepath
length on my system (absolute paths) and that came up with a value
~90 characters.  Assume this is out by a factor of two, we still
have potentially 5000 more arguments that we can put into the buffer.

Surely one might run xargs(1) on something that is not a filename.
We just choose to accomodate the common use-case as much as possible.

[1] find / 2>/dev/null | awk '{print length($0)}' \
	| awk '{a+=$1}END{print "average filepath length: ",a/NR}'

fbd786d22a Correctly handle leftover input
We cannot rely on ungetc() pushing back more than 1 character
reliably on all systems, so just note if we have leftover input and
process it in the next run.

We still have a few error codes to do, namely when the process

3b3dffd24f _brk, _argc and _argv are reserved for the implementation
Thanks to nsz@port70.net for reporting this, the mail excerpt below.

"actually __.* and _[A-Z].* are reserved for any usage and _.* is
reserved for file scope identifiers"

We just rename them to brk_, argc_ and argv_.
