  • Is this the only place you get spurious spaces? Commented Nov 4, 2010 at 9:59
  • I even get many more of these annoying spaces when I compile your document and view it in acroread. I'll add a few lines to your code above, so that it compiles. OK? (Not sure if your document looks the same. By the way, which pdf viewer do you use?) Commented Nov 4, 2010 at 10:06
  • For now this is only place that I notice. Problem is that this is quite important. Alternative is to use standard verbatim but then I wouldn't get color coding that listings provide. I'm reading pdf in Acrobat Reader. Commented Nov 4, 2010 at 10:13

    I can confirm this. In fact, I gat many more extra spaces, the first line looks like this: SELECT S T _ A r e a ( t h e _ g e o m ). As far as pdf viewer goes, I tried zathura, xpdf, evince and acroread with the exact same result. Converting the document with pdftotext also produces the spaces. Commented Nov 4, 2010 at 12:22

    Interesting thing is that when I use latex to produce dvi, and cut and paste from that, I get spurious spaces only around the parentheses and the quotes. Converting that to pdf with dvipdfm inserts all the other spaces, the same I get when using pdflatex. Commented Nov 4, 2010 at 12:26
