Add link fragment that expands to an index entry
When writing indices using overrides—see #167 and #168—it would be nice to have a way to include a reference to a symbol that generates the same output as an index entry, e.g.
[doc@GLib.access]
would become:
<div class="section-item">
<div><a class="symbol" href="func.access.html">access</a></div>
<div>
<p>A wrapper for the POSIX access() function. This function is used to test a pathname for one or several of read, write or execute permissions, or just existence.</p>
<p><span class="emblem available">since: 2.8</span></p>
</div>
</div>
