Bug#459399: vim does not see lage files and overwrites them as new on :wq

[Frederik Schwarzer]

Package: vim
Version: 1:7.1-175+2
Severity: normal

I have a large xml file (12,7 GiB) which I wanted to open in vim to
check some things before sending it to a parser we use.
vim says
'file.xml' [New File]
and shows an empty buffer.
When I now (accidently) executed ":wq", vim overwrote the large xml
file.

Well, actually the second part is kinda expected (though unfortunate)
but it would be nicer if vim saw large files in some more obvious way,
e.g. giving a warning message or something if it doesn't want to open
the file.

For the case this is a fs issue, I run ext3 here.

regards
