An answer I posted ages ago was recently edited, and so I took a quick peek to see what had changed. The alteration was to capitalisation of 'MiKTeX', etc., which would normally be fine. However, the relevant parts were quotations, where I was pointed to what someone else had said (in comments). As such, I'd kept exactly the format they had originally used.
My question is therefore what the 'correct' approach is when quoting: do we stick with the original even if it's non-standard, or do we always standardise formatting (and presumably spelling)? Both approaches seem reasonable to me, so I'd like to see what the overall feeling is.
Note: If I'd been quoting another question or answer, it would be OK to tidy up the source and so the quote too. However, non-mods can't edit comments, so the situation seems a little different.
