QSettings ini file parser does not handle indentation after comment

after a line containing a comment, the next line's leading whitespace is not removed.

bug is in qtbase\src\corelib\io\qsettings.cpp, function readIniLine.

comment is consumed at line 1626 of qsettings.cpp (5.9.0):

while (i < dataLen && (((ch = data.at) != '\n') && ch != '\r'))

but whitespace is only consumed at the start of the function.

Minimum example to reproduce:

#include <QSettings>

int main(int argc, char *argv[])
{
	QSettings ini("test.ini", QSettings::IniFormat);
	ini.beginGroup("FOO");
	bool ok;
	ini.value("bar").toInt(&ok);
	Q_ASSERT(ok);
}

working test.ini file:

[FOO]
;bar = 1
bar = 2

non-working:

[FOO]
;bar = 1
	bar = 2
