Steps to reproduce the issue

Have a language .ini file with the following string.

PLG_ACCESSMESSAGE="This location must be accessible to PHP.<br/>
Your <i>open_basedir</i> configuration in <i>php.ini</i> may restrict this."

Expected result

Language file parsed OK.

Actual result

Language file parsed OK in 4.4.0 but not in 4.4.1

Remove the new lineline in the text and language file now parses.

PLG_ACCESSMESSAGE="This location must be accessible to PHP.<br/>Your <i>open_basedir</i> configuration in <i>php.ini</i> may restrict this."

System information (as much as possible)

Additional comments

libraries/src/Language/LanguageHelper.php
Why has INI_SCANNER_RAW been added to parse_ini_file / parse_ini_string on lines 423, 425?

@parse_ini_file($fileName, false, INI_SCANNER_RAW);

Works in most cases, but got a couple of extensions where it fails to parse the language file.

Example parses OK
PLG_ACCESSMESSAGE="This location must be accessible to PHP.<br/>Your <i>open_basedir</i> configuration in <i>php.ini</i> may restrict this."

Exampe does not parse
PLG_ACCESSMESSAGE="This location must be accessible to PHP.<br/>
Your <i>open_basedir configuration in <i>php.ini may restrict this."
