committed to tl (also the \legend changes), r43490.

One problem with always using quotes is that then filenames with quote chars fail. I think this is why it is not done in the graphics package; I think grffile tries to work around this.

Admittedly quotes are hardly ever used in comparison with spaces, so maybe there are other reasons. Anyway, it's a well-known issue (for umpteen years) so I'm not inclined to bring it up with them again. If anyone wants to, feel free :) ... https://github.com/latex3/graphics-def.

What's really needed is a feature in eTeX to delimit filenames by catcode 1/2 tokens. Maybe someday ...

I've found strange issue with images whose filenames contain spaces (I know that it isn't a good idea, but sometimes you can't control your input):

\documentclass{article}
\usepackage{graphicx}
\usepackage[space]{grffile}
\DeclareGraphicsExtensions{.jpg}
\begin{document}

\includegraphics{"includes/Newman Crest"}
\includegraphics{includes/Newman\space Crest}
\includegraphics{includes/Newman Crest.jpg}
\includegraphics{includes/Newman\space Crest.eps}

\end{document}

It produces the following code

<!--l. 7--><p class="noindent" ><img 
src=""includes/Newman Crest".jpg" alt="PIC"  
width="135.50624pt" height="200.75pt"  />  Crest.xbb <img 
src="includes/Newman Crest.jpg" alt="PIC"  
 />  Crest.xbb <img 
src="includes/Newman Crest.jpg" alt="PIC"  
 /> <img 
src="pathissue0x.png" alt="PIC" class="graphics" /><!--tex4ht:graphics  
name="pathissue0x.png" src="includes/Newman Crest.eps"  
-->
</p>

The issue with first image is that the quotes used in the filename messes with the quotes in HTML attributes, so the file isn't loaded properly. Second and third examples produces spurious `Crest.xbb` text. The last one has wrong resolution and the image is clipped, so only small part of it is displayed.

I've modified the tex4ht sources to remove the quotes from the filename, which fixes the first issue. The second issue might be actually bug in the Graphics package. It tries to open the .xbb file with image dimensions, when it contains spaces, it tries to open only the part before space, the rest will end in the document. I've patched \Gread@eps macro to always include the quotes for .xbb loading. The last issue disappeared almost magically with these fixes, I am not really sure how :)

Simple testing file is attached.
