Escape backslash in xo_emit.3 so it renders correctly

[rwatson]

The unescaped "\n" in xo_emit.3 generates incorrect output when rendered:

           xo_emit(" {:lines/%7ju} {:words/%7ju} "
                   "{:characters/%7ju} {d:filename/%s}0,
                   linect, wordct, charct, file);

This change escapes as "\en" so that the example code renders correctly.

I have a fix in the "develop" branch changing the "\n" to "\n". Is that sufficient or does it need changed to "\en"?
Either way, I'll need to spin a new release and import it into freebsd.

Thanks,
Phil

I'm afraid those both look the same to me. In my original patch I wrote "\n" and it rendered right, but on reading the nroff documentation, \en is preferred, it appears. But we could ask someone who actually understands nroff for their opinion?

Fixed in 'develop'
