21:45		Fix the "fossil timeline" command so that it works with the new EVENT.COMMENT format for wiki page changes. Ticket [4e558dbf3d2511ce]. check-in: 471443b464 user: drh tags: trunk
21:22		Change the way that wiki edits are stored in the Event table in order to address ticket [4e558dbf3d2511ce]. The Event.comment field for a wiki page change now stores just the raw name of the wiki page prefixed with a single character "+", "-", or ":" to indicate if the page was added, deleted, or modified, respectively. Formatting is handled by the timeline rendering. <b>A "fossil rebuild" is required.</b> The "timeline" command is not yet fixed. check-in: 1a9b1c4de7 user: drh tags: trunk

I have created a wiki page with a single quote character in the title on my site. When I look at the timeline, the link to the wiki page is broken: the single quote is escaped twice.

<span class='timelineModernComment'>
Changes to wiki page <a href="/wiki?name=Goethe%26%2339%3Bs+Poems+translated+by+Paul+Dyrsen">Goethe&#39;s Poems translated by Paul Dyrsen</a>
</span>

It is also a problem to link to this page with the [](wiki:) syntax. [foo](Goethe's Poems translated by Paul Dyrsen) translates to <a href="/wiki?name=Goethe%27">foo</a>. Escaping the single quote with a slash does not change that.

A fresh Fossil repository with the issue.

get_link_inline recognizes quote as start of title. This code tries to accept escaped quote.
