Word wrapping of code output

Code is put into the pre div instead of p (normal text). The former does not have word wrap enabled and this might cause text to overflow the slide. I (@pat-s) am not aware of any working R-based solutions (e.g. knitr options) right now.

To prevent that, turn on word wrap in the pre div by using the following CSS redefinition:

pre {
  white-space: pre-wrap;
}

Without word wrap

With word wrap

Indent

The following CSS changes two things:

.remark-code-line {
	white-space: pre-wrap;
	padding-left: 1.85em;
	text-indent: -1.85em;
}

• Only elements with remark-code-line class, and not all <pre> elements, are wrapped
• Adds indent that corresponds to approximately three characters in the default font. (Reference: https://stackoverflow.com/a/480596/946850)
