JS: QUOTES.TXT is deleted when console.editfile() is called

As I've been working on my news reader door for Synchronet (in JS), I've recently noticed something else about console.editfile(). I've been using that to allow the user to edit a message just before posting it in a newsgroup. I now have my news reader writing a QUOTES.TXT in the user's node directory so that the message editor can read that and allow the user to quote the message they're replying to. However, I've noticed that when console.editfile() is called, QUOTES.TXT is deleted (thus, the editor is unable to quote any of the message). I'm wondering if that's by design? If so, is there (or could there be) a way to have it not delete QUOTES.TXT when console.editfile() is called?
