Sync final and leading newlines

This patch adds some missing newlines, trims some multiple redundant
final newlines into a single one, and trims few redundant leading
newlines.

Sync final and leading newlines

This patch adds some missing newlines, trims some multiple redundant
final newlines into a single one, and trims few redundant leading
newlines.

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.

Remove unused Git attributes ident

Remove unused Git attributes ident

The $Id$ keywords were used in 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.

anchor quickref.php regex

The previous regex stumbled on some pages. For example,
reflectionfunction.construct.php was included in the list since
it matches function.<something>.php

Added default google CSE search.

Used our standard includes format (which uses DOCUMENT_ROOT)

Panic, and hacked in a custom google search until this bing-is-no-longer-free issue is resolved.

Get rid of the nasty table here and start adding more of the
"Other ways to search" links to get closer to this being the
one true initial landing page for the redesign.

notfound is already escaped inside manual-lookup.php, so it was escaped twice. Bug discovered by Chris Jones

Added rudimentary search snippets feature. Common searches result in snippets of text. See also the comments. And feel free to improve the text.

Add a limited intermediate result display cache

Right float the bing attribution

Make this page a bit more compact so it is easier to scan for actual content
