This patch adds some missing newlines and trims multiple newlines into
one.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.

The `$Id$` keywords were used in CVS and Subversion where they can be
substituted with filename, last revision number change, last changed
date, and last user who changed it.
In Git this functionality is different and can be done with Git
attribute ident. These need to be defined manually for each file in the
`.gitattributes` file and are afterwards replaced with 40-character
hexadecimal blob object name which is based only on the particular file
contents.
This patch simplifies handling of `$Id$` keywords by removing them since
they are not used anymore.
I know that this could have been way simpler but I just wanted this working
and it seems to do it's job well
Suggestions and improvements are very welcome, this is more a quit draft.
Updating the script in phpdoc/scripts/ is on my large TODO list, it only
requires the SQLite cache system though..
The first script run should be done by hand. If the script dies with "EOF"
you will have to re-run the script, the news server has disconnected you.
