Sorry, I forgot to remove Xlarge.txt after the test. (It was useful when I debug
these patches, but it is not needed now.)
And now we have the num64 feature, we can use the number 4000000000 directly
in test_largefile.vim for checking the filesize.
(Or, is it better to check more large file (> 2^32 bytes)?)
Please check the attached patch.
Regards,
Ken Takata
