cc2d762798 Use the width of the output device by default in mc(1) 
If that fails, fallback to 65 characters as before.  If the -c
option is specified then just use that.

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.
