#2622 shell commands are not executed correctly

[U_Fischer]

This was discovered while investigating why minted doesn't work correctly in miktex.

This document fails in miktex when compiled with --shell-escape. The folder is not created:

\documentclass{article}

\begin{document}
\immediate\write18{if not exist blubfolder mkdir blubfolder}

\end{document}

The messages on the command line (""exist"" kann syntaktisch... ) indicates that the argument isn't processed correctly:

G:\Z-Test>pdflatex --shell-escape test-utf8

A similar message can be seen for a shell command starting with a for loop.

In texlive the document compiles fine and creates the folder.

Should be ok now/

Has the fix also been added to miktex next? I don't get any updates there.
