/**
- * Renders comment(s).
- *
- * @param $node
- * The node which comment(s) needs rendering.
- * @param $cid
- * Optional, if given, only one comment is rendered.
- *
- * To display threaded comments in the correct order we keep a 'thread' field
- * and order by that value. This field keeps this data in
- * a way which is easy to update and convenient to use.
- *
- * A "thread" value starts at "1". If we add a child (A) to this comment,
- * we assign it a "thread" = "1.1". A child of (A) will have "1.1.1". Next
- * brother of (A) will get "1.2". Next brother of the parent of (A) will get
- * "2" and so on.
- *
- * First of all note that the thread field stores the depth of the comment:
- * depth 0 will be "X", depth 1 "X.X", depth 2 "X.X.X", etc.
- *
- * Now to get the ordering right, consider this example:
- *
- * 1
- * 1.1
- * 1.1.1
- * 1.2
- * 2
- *
- * If we "ORDER BY thread ASC" we get the above result, and this is the
- * natural order sorted by time. However, if we "ORDER BY thread DESC"
- * we get:
- *
- * 2
- * 1.2
- * 1.1.1
- * 1.1
- * 1
- *
- * Clearly, this is not a natural way to see a thread, and users will get
- * confused. The natural order to show a thread by time desc would be:
- *
- * 2
- * 1
- * 1.2
- * 1.1
- * 1.1.1
- *
- * which is what we already did before the standard pager patch. To achieve
- * this we simply add a "/" at the end of each "thread" value. This way out
- * thread fields will look like depicted below:
- *
- * 1/
- * 1.1/
- * 1.1.1/
- * 1.2/
- * 2/
+ * get number of new comments for current user and specified node
*
- * we add "/" since this char is, in ASCII, higher than every number, so if
- * now we "ORDER BY thread DESC" we get the correct order. However this would
- * spoil the reverse ordering, "ORDER BY thread ASC" -- here, we do not need
- * to consider the trailing "/" so we use a substring only.
+ * @param $nid node-id to count comments for
+ * @param $timestamp time to count from (defaults to time of last user access
+ * to node)

+ * Renders comment(s).
+ *
+ * @param $node
+ * The node which comment(s) needs rendering.
+ * @param $cid
+ * Optional, if given, only one comment is rendered.
+ *
+ * To display threaded comments in the correct order we keep a 'thread' field
+ * and order by that value. This field keeps this data in
+ * a way which is easy to update and convenient to use.
+ *
+ * A "thread" value starts at "1". If we add a child (A) to this comment,
+ * we assign it a "thread" = "1.1". A child of (A) will have "1.1.1". Next
+ * brother of (A) will get "1.2". Next brother of the parent of (A) will get
+ * "2" and so on.
+ *
+ * First of all note that the thread field stores the depth of the comment:
+ * depth 0 will be "X", depth 1 "X.X", depth 2 "X.X.X", etc.
+ *
+ * Now to get the ordering right, consider this example:
+ *
+ * 1
+ * 1.1
+ * 1.1.1
+ * 1.2
+ * 2
+ *
+ * If we "ORDER BY thread ASC" we get the above result, and this is the
+ * natural order sorted by time. However, if we "ORDER BY thread DESC"
+ * we get:
+ *
+ * 2
+ * 1.2
+ * 1.1.1
+ * 1.1
+ * 1
+ *
+ * Clearly, this is not a natural way to see a thread, and users will get
+ * confused. The natural order to show a thread by time desc would be:
+ *
+ * 2
+ * 1
+ * 1.2
+ * 1.1
+ * 1.1.1
+ *
+ * which is what we already did before the standard pager patch. To achieve
+ * this we simply add a "/" at the end of each "thread" value. This way out
+ * thread fields will look like depicted below:
+ *
+ * 1/
+ * 1.1/
+ * 1.1.1/
+ * 1.2/
+ * 2/
+ *
+ * we add "/" since this char is, in ASCII, higher than every number, so if
+ * now we "ORDER BY thread DESC" we get the correct order. However this would
+ * spoil the reverse ordering, "ORDER BY thread ASC" -- here, we do not need
+ * to consider the trailing "/" so we use a substring only.
