file.Find includes files with excess ~s for no reason.

I've started sharing my lua files with my netbook so I can code when I get bored on the go.
However, since it uses linux, it has an annoying habit of creating backups with ~s on the end of their filename, which dropbox picks up and shares, meaning they end up in my gamemodes folder.
I wouldn't really care about this if it wasn't for the fact that file.FindInLua seems to think that sv_entity.lua~ matches the pattern "*.lua", which it quite clearly doesn't.
I tested if it was including anything after the pattern by searching for "*.lu", but that came up with nothing.
So why is this happening, and how do I stop it, other than routinely culling the unwanted files?

Try placing this in autorun:

[lua]local FindInLua = file.FindInLua

function file.FindInLua(path)
local tab = FindInLua(path)
local ext = path:match(".+%.(.+)$")
if not ext then
return tab
end
for k, f in ipairs(tab) do
if !f:find(".+%."..ext.."&") then
table.remove(tab, k)
end
end
return tab
end[/lua]

Untested code, so probably fails.
