"Stand-alone" versions of "month in year" and "day of week" formats more closely mimic strftime in German locale about strftime

[bohwaz]

That seems like a useful change, thanks.

A quick check seems to indicate that in some cases with ccc and LLL the result is more consistent with strftime (see below some locales I had in mind for a quick test). For example for finnish and russian. In most cases it doesn't change anything from MMM/EEE.

So I'd say go for it :)

What would be useful would be to have a test that generates all local date strings using \strftime and this replacement library and find out which locales have different returns.

<?php

$locales = ['pl_PL', 'fr_FR', 'de_DE', 'nl_NL', 'nl_BE', 'de_CH', 'fr_CH', 'fr_BE', 'zh_CN', 'ru_RU', 'fi_FI', 'sv_SE', 'no_NO', 'ro_RO', 'cs_CZ', 'es_ES', 'pt_PT', 'pt_BR'];

foreach ($locales as $locale) {
	echo "$locale\n";
	$locale .= '.UTF-8';
	setlocale(LC_ALL, $locale);
	$i = function($f) use ($locale) {
		var_dump((new \IntlDateFormatter($locale, \IntlDateFormatter::FULL, \IntlDateFormatter::FULL, null, null, $f))->format(new DateTime('1 month ago')));
	};
	var_dump(@strftime('%a %A %b %B', strtotime('1 month ago')));
	$i("EEE EEEE MMM MMMM");
	$i("ccc cccc LLL LLLL");
	setlocale(LC_ALL, 'C'); // Restore locale to detect locales that are not installed
}
