[modules / vcs-to-changelog] Wrong filename path if spaces in file name.

[Thierry Bothorel]

Hi,

this is a sample output I get:

> 2020-05-03 THBO <xxxxxxxxx@xxxxxxxxxxxxxxxx>
>
> COMMIT: 1d02a74a93dfcb7822a0ddb1bb003db18fae4c72
> Message sample.
>
> * Modele/Datawarehouse/GesCom/Vente.mdl: Modified.
> * Modele/Datawarehouse/Gescom: Modified.
> * Modele/Datawarehouse/Gescom: Modified.
> * Modele/Gescom1/F: Modified.
> * Modele/Gescom1/F: Modified.

whereas the good output is:

> 2020-05-03 THBO <xxxxxxxxx@xxxxxxxxxxxxxxxx>
>
> COMMIT: 1d02a74a93dfcb7822a0ddb1bb003db18fae4c72
> Message sample.

> * Modele/Datawarehouse/Gescom conso/F vente.mdl: Modified.
> * Modele/Gescom1/F achat.mdl: Modified.
> * Modele/Gescom1/F vente.mdl: Modified.
