Hello,
To reproduce:
:!echo -n 'Hello' >temp.txt
:echo readfile('temp.txt')
Then an empty list is displayed rather than the content of this file.
The attached patch fixes this problem.

Hello,
The last patch has some problem. Use this patch instead.
The solution is, when readfile() in text mode, if we reach the end of
the file and we still didn't find a NL, then add an NL to the end of the
buffer.
