doc: rename README to README.rst Many hosting services consider README without extension as plain text. By using .rst extension, we bring better formatting on many services (e.g. bitbucket).

test: use current user in the multi-user amend scenario The obsfate template keyword that will be introduced in a later patch distinguish between current user and other users when displaying the obsfate users. Update the test before for clarity.

test: cleanup verbosity variant from fatelog test Unlike the '{obsfate}' keyword defined in 'hg-evolve', the definition of hg fatelog in test-obsmarker-template.t is not verbosity dependent. Remove useless call to fatelog -v and fatelog -q.
