[texworks] SCRIPTING: Get content of specified directory

[Paul A Norman]

Looking really awesome Henrik!

Haven't tried all scenarios yet, but really like the precision of
operation, and the clarity of coding - made it really easy for me to
try and get it running under Windows for your new feature - input of
filenames.

Often people have asked here whether there could be an automatic
completion of environments

\begin{something}   sa a s a sad sad  fd f
<contorl-key M>

\begin{ofsomething}   sa a s a sad sad  fd f
\end{ofsomething}

Is that something that you would see possibly logically fitting in
with your code at all?

With your new code, under Windows - I've tried these alterations, I
don't think they'd break the Linux version (?)

Quotes for possible spaces in file path (platform tested), and I've
found that for *some* Dos commands and utilities we need to absolutely
reverse the path delimiter to a backslash - fickle problem, and safer
to actually sample the output to determine whether \n or \r\n is doing
the line breaks and not assume it on platform.

Regards,
Paul

	return retVal.output;

 }
