We need to return Regexp.escape(camel_cased_word)
if the split is blank.

Revert "Changed the CHANGELOG for active_support and improved the doc for inflector method classify"

This reverts commit 8d5fcb69.

Reason: Changelogs are not to be edited in docrails.

[ci skip]

`active_support/inflections` already requires
`active_support/inflector/inflections`. There's no need to require it in
`active_support/inflector/methods`.

This reverts commit 867dc170, reversing
changes made to 9a421aaa.

Fixed a bug where the inflector would replace camelCase strings and disregarding specified acronyms, fixes #8015

The Inflector is currently not very supportive of internationalized
websites. If a user wants to singularize and/or pluralize words based on
any locale other than English, they must define each case in locale
files. Rather than create large locale files with mappings between
singular and plural words, why not allow the Inflector to accept a
locale?

This patch makes ActiveSupport::Inflector locale aware and uses `:en`` unless
otherwise specified. Users will still be provided a list of English (:en)
inflections, but they may additionally define inflection rules for other
locales. Each list is kept separately and permanently. There is no reason to
limit users to one list of inflections:

    ActiveSupport::Inflector.inflections(:es) do |inflect|
      inflect.plural(/$/, 's')
      inflect.plural(/([^aeéiou])$/i, '\1es')
      inflect.plural(/([aeiou]s)$/i, '\1')
      inflect.plural(/z$/i, 'ces')
      inflect.plural(/á([sn])$/i, 'a\1es')
      inflect.plural(/é([sn])$/i, 'e\1es')
      inflect.plural(/í([sn])$/i, 'i\1es')
      inflect.plural(/ó([sn])$/i, 'o\1es')
      inflect.plural(/ú([sn])$/i, 'u\1es')

      inflect.singular(/s$/, '')
      inflect.singular(/es$/, '')

      inflect.irregular('el', 'los')
    end

    'ley'.pluralize(:es)   # => "leyes"
    'ley'.pluralize(:en)   # => "leys"
    'avión'.pluralize(:es) # => "aviones"
    'avión'.pluralize(:en) # => "avións"

A multilingual Inflector should be of use to anybody that is tasked with
internationalizing their Rails application.

make sure the inflection rules are loaded when cherry-picking active_support/core_ext/string/inflections.rb [fixes #6884]

This reverts commit fa6d921e.

Reason: Not a fan of such massive changes. We usually close such changes
if made to Rails master as a pull request. Following the same principle
here and reverting.

For future reference, this is the regex I used: ^\s*#\s*\n(?!\s*#). Replace
with the first match, and voilà! Note that the regex matches a little bit too
much, so you probably want to `git add -i .` and go through every single diff
to check if it actually should be changed.

The regexp used in titleize matches saxon genitive
and other contractions, only to call capitalize on
the captured text and have the apostrophe upcased
which yields the apostrophe itself. It is more
clear that the regexp matches just what it has to
match.

The impact of this change has been measured pluralizing
the entire /usr/share/dict/words, showing a 6x speedup

Use ActiveModel::Errors in inflection example docs as well.

Also fixes wrong information and link to locale file related to
Errors#full_messages in I18n guide.
