Arbitrary long file lists?

Hi,

commands like git-archive take a file list on the command line. If the number of files does no longer fit the argv limitations, this causes a problem.

So it might be nice to be able to treat some "filenames" in a file list special:

-@=filename (read LF-lines with filenames from filename) -@=- (read lines with filenames from stdin) -@z=filename (read NUL-terminated list with filenames from filename) -@z=- (same from stdin)

Of course, this particular syntax, very loosely inspired by infozip, leaves a lot to be desired: prettier proposals welcome.

But the feature itself would not be unimportant. I am also fuzzy on what sort of quoting should be interpreted outside of the NUL-terminated case.
