grep: enable all-files by default (BC)

Summary

This patch deprecates the --all-files flag and make the all-files
behaviour as default.

In test-grep.t, I removed '--all-files' from every command where it was
used, to reflect that all-files behaviour is default and there is no
change even after the removal.
And other changes in test files are because of changed behaviour.

The docstring needs an update too.

No longer by default! Or perhaps at all.

The docstring needs a significant update too. Would you like me to suggest something?

Sure :)

How about something like this?

grep: update docs to reflect new --all-files default

These docs no longer even mention the old weird behaviour that was
poorly understood and underutilised. I think this undocumentation
effectively deprecates it.
