Before: libsystemd-daemonpkg-config(1) After: libsystemd-daemon pkg-config(1) This fix is more complicated than it should be due to the consecutive XML elements separated by collapsible whitespace. Merging the lines and separating the XML elements with an en space or a non-breaking space is the only solution that results in one, and only one, space being inserted between them when testing. An em space results in two spaces being inserted.

<title>Description</title>

<para><filename>sd-journal.h</filename> provides APIs
|

to submit and query log entries. The APIs exposed act

both as client for the
|
||
<citerefentry><refentrytitle>systemd-journald.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
||
journal service and as parser for the journal files
|
||
on disk.
