Extra space added by \code as defined in packages/url

[jmaibaum]

Using SILE 0.10.10, and typesetting the following example:

\begin{document}
\script[src=packages/url]
The \code{\\code} command defined in \code{packages/url} typesets an extra space at the end, see:
\url{https://github.com/sile-typesetter/sile/blob/bd7e52e75663b861ee0bb57876204e740f518fbc/packages/url.lua#L47}.
Most likely I simply don’t know the use cases this extra space enables, but to the casual user,
this looks like a clear bug.
\end{document}

produces this output:

sile/packages/url.lua

Line 47 in bd7e52e

SILE.typesetter:typeset(" ")

Commenting out the line locally fixes the example above:

Does not typesetting this extra space break important stuff elsewhere?

I stumbled upon this while trying out @alerque's WIP SILE writer for pandoc PR where using the standard markdown backticks syntax ends up using the \code command from packages/url.

In case this is considered a bug, I have just filed a quick PR.

That looked pretty bizarre to me. I was even more chagrined to run git blame on the original \code function and find it tracked back to my commit 50fc3b3 with no explanation for the space.
