#190 Redundant space in PDF metadata

[note286]

I found a typo in pdf metadata, as shown in the below console output. I found it may be caused by redundant space in line 14557 in xetex.web file. It should be print("XeTeX output "); but not print(" XeTeX output ");. Besides, I found that this problem has always existed and has never been corrected.

% xelatex 1.tex
\documentclass{standalone}
\begin{document}
1
\end{document}
