* Leading spaces are lost when pulling bug #2571
Reason: during the pull (deserialization), the method `PARSE` of `ZCL_ABAPGIT_XML` does a `li_parser->set_normalizing( iv_normalize )` whose parameter has the default value "true", which strips leading and trailing spaces.
Solution: use `li_parser->add_strip_space_element( )` instead of using the normalization, which seems to work in elementary objects (clas, devc, doma, dtel, enho, enqu, fugr, intf, prog, scp1, tabl, tran, ttyp), but I fear of side effects throughout all abapGit features.
* #2571 zcl_abapgit_xml iv_normalize removed+AU
- Removal of useless parameter IV_NORMALIZE of method PARSE
- Abap Unit test added for testing the method PARSE for an XML valuecontaining leading and trailing spaces
* renaming attribute lo_xml to mo_xml
