doc: interpret-trailers: don’t use heredoc in examples
This file contains four instances of trailing spaces from its inception in commit [1]. These spaces might be intentional, since a user would be prompted with `> ` in an interactive session. On the one hand, this is a whitespace error according to `git diff --check`; on the other hand, the raw documentation—it makes no difference in the rendered output—is just staying faithful to the simulation of the interactive prompt. Let’s get rid of these whitespace errors and also make the examples more friendly to cut-and-paste by replacing the heredocs with files which are shown with cat(1).
