bug#6903: join: improve paralleles to sort?

[Bernhard Schiffner]

Hi,

having to work with lists containing lage numbers (i.e. filesizes greater 2GB) 
I have problems.
sort -n works
join dosen't  do as a "newcomer" expects.

Because join uses strtoul() before doing comparisation it is understandable. 
("unpairable" is the result.)

Do you see a chance to extend join with a -n parameter for numeric 
comparisation as sort has already?

In the source / manpage  join claims about combinations with sort. Why not 
expand this? :-)

TIA!

Bernhard
