Hi,

is this ok to push?  I gathered the information myself by experimenting with
the GCC Bugzilla and reading the Bugzilla documentation page I link to in the
patch. Html validated with validator.w3.org.

Thanks,
Filip Kastl

+<h2>Bugzilla tips and tricks</h2>
+
+<h3>Automatic linking</h3>
+
+<p>When writing a description of a new bug or commenting on an already existing
+bug, you can make use of certain shortcuts to link to other bugs, commits,
+comments and similar stuff.  Here is a (most likely incomplete) list of these
+shortcuts:</p>
+
+<h4>Bugs, comments and attachments</h4>
+<ul>
+  <li>A string <code>pr XXXX</code> or <code>bug XXXX</code> where
+    <code>XXXX</code> is a Bugzilla bug ID automatically gets turned into a
+    link to the appropriate bug page.</li>
+  <li><code>attachment X</code> will link to the attachment with ID
+    <code>X</code>.</li>
+  <li><code>comment X</code> gets turned into a link to the <code>X</code>-th
+    comment under <i>this</i> bug.</li>
+  <li>You can use <code>bug XXXX, comment Y</code> to link to a comment
+    under a different bug.  Using <code>pr</code> doesn't work here.</li>
+</ul>
+These shortcut keywords are case-insensitive.  Except for the
+<code>pr</code> keyword, these are actually not specific to GCC Bugzilla.
+See <a
+href=https://bugzilla.readthedocs.io/en/latest/using/tips.html#autolinkification>
+Bugzilla documentation</a>.
+
+<h4>Commits</h4>
+<ul>
+  <li><code>g:XXXXXXX</code> where <code>XXXXXXX</code> is a prefix of the
+    hash of a commit links to
+    <code>https://gcc.gnu.org/cgit/gcc/commit/?id=XXXXXXX</code>.  The
+    prefix must be at least 7 characters long.</li>
+  <li><code>rXX-YYYY</code> links to
+    <code>https://gcc.gnu.org/cgi-bin/gcc-gitref.cgi?r=rXX-YYYY</code>.  So
+    this way you can link to the <code>YYYY</code>-th commit of GCC version
+    <code>XX</code>.</li>
+  <li>Combining the two variants is also possible:
+    <code>rXX-YYYY-gZZZZZZZ</code> will link to
+    <code>https://gcc.gnu.org/cgit/gcc/commit/?id=ZZZZZZZ</code>. So the
+    <code>gZZZZZZZ</code> takes precedence.  Btw, you can use the script
+    <code>contrib/git-descr.sh</code> from the GCC's source tree to convert
+    commit hashes to this format.</li>
+</ul>
