bug#3788: 23.0.95; nxml-mode: close-start-tag-block == close-start-tag-inline

[Rommerskirchen, Heinrich (NSN - DE/Munich)]

nxml-balanced-close-start-tag-block doesn't work as advertised. It
doesn't
insert a line break, even if the start-tag is on a line by its own.
Instead it
behaves like nxml-balanced-close-start-tag-inline.

To recreate it:
start emacs with '-Q'
open (C-x C-f) non existing file tmp.xml
enter 'M-x nxml-mode'
type '<a'
enter C-c C-b
Now the buffer contains one line '<a></a>' with the cursor between the
two tags.

In emacs 22.3 with nxml-mode-20041004, the same recipe
(plus '(load-library "rng-auto.el")' before calling nxml-mode) gives the
expected three lines (start tag, empty line, end tag) with the cursor at
the
correct place, i.e. at the empty line.
