Fix trimming leading whitespaces
As in #1534 (closed) described, currently OL does not strip leading whitespaces during OpenLyics import. This is a regression introduced with d2cf191d (or bd811c2b?).
Currently this OpenLyrics XML code...
<lines>
The <chord name="G"/>splendor of the <chord name="D/F#"/>King<br/>
<chord name="Em7"/>Clothed in majesty<br/>
Let all the earth <chord name="Cmaj7"/>rejoice<br/>
All the earth rejoice<br/>
He <chord name="D"/>wraps <chord name="G"/>Himself in <chord name="D/F#"/>light<br/>
And <chord name="Em7"/>darkness tries to hide<br/>
And trembles at His <chord name="Cmaj7"/>voice<br/>
And trembles at His <chord name="D"/>voice
</lines>
...produces:
The [G]splendor of the [D/F#]King
[Em7]Clothed in majesty
Let all the earth [Cmaj7]rejoice
All the earth rejoice
He [D]wraps [G]Himself in [D/F#]light
And [Em7]darkness tries to hide
And trembles at His [Cmaj7]voice
And trembles at His [D]voice
With this patch the imported value is:
The [G]splendor of the [D/F#]King
[Em7]Clothed in majesty
Let all the earth [Cmaj7]rejoice
All the earth rejoice
He [D]wraps [G]Himself in [D/F#]light
And [Em7]darkness tries to hide
And trembles at His [Cmaj7]voice
And trembles at His [D]voice
