I found another HTML typo, and replaced a <u></u> by <strong></strong> because <u> does not validate as 'XHTML 1.0 stict'.

- Patch #15948 by matteo: the book module should call the nodeapi hook when printing printer-friendly pages.

- Patch #15976 by Neil: if one single admin modifiable menu item is added then it is not put in the menu table because the comparison is > 1 instead of > 0.

- Patch #14936 by Junyor: the 'add comment link' was not available for polls.

- Patch #15690 by Goba: the vocabulary node types checks in taxonomy.module are very vulnerable to having node types names as prefixes of other node type names %%%s%% as it is there with %%blog%% will match a lot more, then just this simple node type.  Since the node types are stored in a comma separated list, the solution is to search for 'blog' or '%%,blog,%%' or 'blog,%%' or '%%,blog', that is matching only for that node type, or matching that node type in a list, or at the beginning of a list, or at the end of a list. It does not look elegant, but this is the solution for the format used.
