get_pagenum_link() returns URL with pagination base for a singular paged content

[szepe.viktor]

on this page I use an own plugin by a shortcode:

http://www.online1.hu/webdesign/

get_pagenum_link(2); returns

http://www.online1.hu/webdesign/page/2/

but it should make a difference:
front page: ​http://www.online1.hu/page/2/
other pages: ​http://www.online1.hu/webdesign/2/

Is it as bug??

my front page is a static page
links are: /%year%/%monthnum%/%postname%/

so "page_on_front"

four cases

URLs : get_query_var(), content relative to !--nextpage--

in case of the front page
/2/ : HTTP/404
/page/2/ : paged= page=2, after !--nextpage-- content

in case of a page
/2/ : paged=0 page=2, after !--nextpage-- content
/page/2/ : paged=2 page=, before !--nextpage-- content

get_pagenum_link() shouldn't use $wp_rewrite->pagination_base on single posts

wp_link_pages() is the appropriate function to use for getting paged links for paginated posts as get_pagenum_link() is designed for archive pagination.

Supporting singular pagination in get_pagenum_link() as well might be a good idea though. However, looking at the patch (untested) it looks like it doesn't support pages. So, should it be checking is_singular() and not page_on_front, see _wp_link_page()?

the default condition is everything else, including pages

Patch refreshed to account for 1) search 2) posts / pages except for page on front 3) everything else

Note: wp_link_pages() calls _wp_link_page() which is similar to get_pagenum_link()

This is insane - I patched 2 different tickets and the diff was almost exactly the same. This one's a dupe then.
