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 decided to not describe automated (create-phpdoc-setup.php) option
to make instructions more straightforward, but one can revert it if
it's really needed or helpful.
* "old files" stats were generated incorrectly
* "old files" made "critical files" count incorrect
* there was no way to display "old files" list
* this approach is compatible with PhD OE
