<p>The peculiar use of a single letter to name software, as in <code>C</code>, <code>J</code>, <code>S</code>, and <code>R</code>, cries out for special formatting to help the reader.  Therefore I consistently write "<code>R</code>" instead of "R" and I appreciate posts that do this, too.  Some other packages do have conventional formatting: for instance, "<em>Mathematica</em>" is always italicized on the <a href="https://mathematica.stackexchange.com/">Mathematica site</a>.</p>

<p>As far as edits go (picking up on a comment by @Glen_b), tastes differ, so during reviews I don't apply any particular convention.  I look for consistency in formatting.  I check that proposed edits to reformat text and code do not introduce any errors.  I follow guidelines laid down elsewhere suggesting we should eschew making minor edits, like formatting improvements, in posts that aren't <em>very</em> recent.  During reviews I therefore check that substantive edits are proposed and am grateful for any incidental formatting improvements made <em>en passant</em>.</p>
