Warn before opening large files.

[HT-7]

In Nemo (Linux Mint), unknown file types such as "jsonlz4" are associated with xed, even though they contain binary data not useful to Xed.

When opening a file that is too large in Xed, it hangs up and must be taskkilled, leading to the loss of any unsaved work.

Please warn before opening large files. Thanks.

Notepad on Windows does that too since at least Vista.

Xed does not open those files by default (the archive manager tries to, though in this case, lz4 isn't currently supported).

Any unknown type should get a message if you double-click, asking you to choose a program. You can reset the default action if xed (or any other program) has accidentally been set to open the wrong file type:

• Right-click on the file in nemo
• Select Open with... -> Other application
• Here you should be able reset it to its default handler:

Somehow mine does. Nonetheless, Xed needs to warn before opening large files.
