As in documenting an API or command syntax, when you want to go from mono (literal) to italic (variable input) with no break. In Skriv it would be ##--input=##''filename'' except that (a) Skriv requires a space and even if it didn't, (b) the -- would be an unbalanced strikeout code. Not to worry, reST doesn't do it either.
