pkgdown inserts white space after \doi{..}

[GeoBosh]

pkgdown inserts a line break after rendering \doi{...}. This results in a redundant space when \doi{...} is followed by full stop (or other punctuation).

This was reported as an issue in Rdpack where references ending in doi get a superfluous space between it and the final dot. But this happens only when rendered by pkgdown (R doesn't insert a space in any format).

This seems to be purely a \doi rendering problem. Inserting the following in an Rd file

\doi{10.2307/2413326}.

is rendered as

<a href="https://doi.org/10.2307/2413326" class="external-link">doi:10.2307/2413326</a>
.</p></li>

(don't know what command to use for a reprex, tried pkgdown:::rd2XXX() calls but with no success).

For further examples, see GeoBosh/Rdpack#33 (comment) for the rendered html of several references.
