stand-alone iocamljs kernels doesn't like `split-lines`

[samoht]

It seems stand-alone kernel.foo.js doesn't work with split lines in the code. I got the following error message:

[Error] TypeError: undefined is not a function (evaluating 'string.split(/\r\n?|\n/)')
    (anonymous function) (codemirror.js, line 5481)
    setValue (codemirror.js, line 4689)

Note: I'm not totally sure how to reproduce this one, I got that errors on some notebooks and sometimes not and I'm not clear what is the real cause.

I confirm, having an array instead of a string in source or input seems to cause the problem.

The following patch to static/notebook/codecell.js seems to fix the issue:

-               this.set_text(data.input);
+               if (typeof data.input == "string") { this.set_text(data.input) }
+               else { this.set_text(data.input.join("")) };

See andrewray/iocamlserver#10 for some background to this and the option -no-split-lines for the current solution, also noted here

(note the same fix is needed in textcell.js and maybe in other places)
