Comment characters are based on the `TM_COMMENT_START` etc. environment 
variables.

If you use Bundles → Select Bundle Item… (⌃⌘T) and switch to 
settings, then you can enter `tm_comment` and see the current values for 
these variables.

These would normally come from bundle settings items.

On a clean install of TextMate, opening `foo.json.jbuilder` will treat 
it as plain text.

If you change the language (via the status bar) then TextMate will 
remember this binding, and the default comment characters will follow.

Normally it should only be necessary to set `TM_COMMENT_START` etc. if 
you want to override the default for the language, so simply setting the 
proper language (ruby) for `jbuilder` files should be enough.

Alternatively, you could put something like this in `~/.tm_properties`:

	[ *.json.jbuilder ]
	TM_COMMENT_START = '# '

But the best is to just bind `jbuilder` files to the proper language and 
rely on the defaults.
