[O] Quoting "_" for html and LaTeX output

[Peter Davis]

A lot of the information I track in org-mode includes filepaths and 
names and other strings containing underscore ("_") characters. I'd like 
to be able to quote these for HTML and LaTeX output, so I don't wind up 
with unwanted subscripts.

On the other hand, I want the data to be pretty readable within the org 
buffer, so using \under{} pretty much fails that.

Is there another, more concise way to do this, possible for large 
stretches of text at a time? I don't want to use an example block, as I 
still want to format the text and avoid the mono-spaced font.

I understand that "\_" used to work, but doesn't on more recent 
versions. Any chance of getting that back?

Thanks!
