Version Control With Subversion Source

Delete svnbook pt_BR directory, because it was not copied using a Subversion
copy, but using a manual addition.

Started translation to Brazillian Portuguese from the
trunk. The directory src/en was copied from revision
1922 without keeping history. The property svn:ignore
was properly set at src/pt_BR/book as it is in
src/en/book.

The only translated files committed in this revision
are the following. All other files remain in English
for further translation.

* src/pt_BR/book/foreword.xml
* src/pt_BR/book/book.xml
The only translated files so far.

Ignore a couple of directories in the Norwegian subtree.

* src/nb/
svn:ignore set to "bd.tmp".

* src/nb/book/
Added "eng" to svn:ignore.

Proofreading in the Norwegian svnbook.

* src/nb/TRANSLATION-STATUS
(Proofread): Updated ch05.xml .

* src/nb/book/ch05.xml
Some minor rewrites.

Book Spanish. Translated two paragraphs.

* src/nb/METHOD
(Keeping the translation updated): “make valid” should be enough, no
need to build the whole thing.
(Some make commands): Removed superfluous “make” description.

Book Spanish. Translated one paragraph.

"make bookdiff" changes in the Norwegian book.

* src/nb/Makefile
(bookdiff): If the $(BDTMP) directory exists, it can be removed by
pressing Enter. Also straighten up the output by hiding things.

Norwegian svnbook: Translated some sections.

* src/nb/TRANSLATION-STATUS
ch07.xml to 4%.

* src/nb/book/ch07.xml
Some sections translated.
