Write wrapped messages back

[AlexanderHH]

It looks like by default the strings will be wrapped. Like msgid and translated strings msgstr. Poedit and the unix-command msgmerge write the long strings wrapped. It would be good, if it will be possible to set the additional parameter somewhere, like in the writeFile method. to wrap long strings.

I wrote thid code for my project:

if (is_array($msgstr)) {
	foreach ($msgstr as $n => $mstr) {
		$entry['msgstr[' . $n . ']'] = [];

		$mstr = trim($mstr);

		$subentries = explode("\n", wordwrap($mstr, 75));
		if (count($subentries) == 1) {
			$entry['msgstr[' . $n . ']'][] = $mstr;
		} else {
			$entry['msgstr[' . $n . ']'][] = '';
			foreach ($subentries as $nr => $subentry) {
				$entry['msgstr[' . $n . ']'][] = $subentry . ($nr < count($subentries) - 1 ? ' ' : '');
			}
		}
	}
}

By the way, I have no idea, why in case of multiline (in the .po file) the first entry is the empty string:

#: stuff/xxx.php:12
#, php-format
msgid ""
"%s yyy1 sdf jsdlf slfd lsfd lfj lfdg lfdg dlfgj dlfgj dlgj fdlgjdfl gfdlgj "
"dfgj dflgj dlj glfdg lglk jldfgj fdklgj fdlgj fdgjgl dfgl jglkjg lfdjg "
"lsfdjskl dg 111111111"
msgid_plural ""
