Actually I can't retrieve full file's changelog because when using changelog on file's directory we lost some information if file had been moved from other directory in the past.
Moreover for Git and Hg we need the possiblity to add --follow option to retrieve changelog even if file had been rename/move or whatelse.
So is it possible to enhance changelog api in order to support:
- [API] Changelog single file
- [GIT/HG providers] Add --follow option when changelog a single file
