Language tool is substituting 'false' for some existing values.

[Joe Kavanagh]

1. Goto the a11yhelp plugin's en language file.
2. Copy the accessibilityHelp object to the clipboard.
3. Open the main en language file in the lang folder.
4. Add a comma to the end of the last lang object.
5. Paste in the accessibilityHelp object.
6. Run the langtool to process the file.
7. Open the de language file.

Observe the accessibilityHelp object has property values set to 'false' with the comment MISSING.

If you remove the white-spaces between the open curly bracket and the 'name' property, their values will be copied to the other language files. For example:

legend :

[ {name : 'General',

items : [

{name : 'Editor Toolbar',

I've also seen this occur if a block comment is entered between the language property value and trailing comma. For example:

url: 'URL' /* block comment */,

The a11yhelp language file has not been designed for compatibility with the langtool and it's not compatible with it. This is by design, and it's related to the arrays included in the language entries.
