Note: the implementation is different (better) than what used to be in
Buildroot before source-check was removed.
The original implementation:
hg incoming --force -l1 <URL>
would only verify that the repository exists, not that the requested
revision is present.
An already better implementation is:
hg incoming --force -l1 -r <revision> <URL>
but compared to the next solution it has a large resource consumption on the
local machine. In the background, the full repository is first downloaded.
The implemented solution is:
hg identify -r <revision> <URL>
which operates directly on the remote repository.

- use true/false as values to 'checkonly'
- always check revision, even if no source-check
- replace incorrect 'exit $?' by explicit 'exit 0'
