Re: Tutorial PSF subtraction

Hi Alex,

Thanks again for reporting this portability problem in the tutorial. I 
just implemented your fix in the tutorial so future readers with this 
peculiar version of 'ls' don't have the problem any more:

https://git.savannah.gnu.org/cgit/gnuastro.git/commit/?id=5d3c937813b

It is also good for other users (that have regular 'ls' behavior) 
because their script will be more portable (and will not crash when they 
run their scripts on other computers) :-).

Thanks again,
Mohammad
