errors: raise InputError from revpair() iff revset provided by the user Same reasoning as for `revrange()` in an earlier patch. Differential Revision: https://phab.mercurial-scm.org/D11561

errors: raise InputError on bad revset to revrange() iff provided by the user Most callers of `scmutil.revrange()` pass in a revset provided by the user. If there are problems resolving that, it should result in an `InputError` and exit code 10 (when using detailed exit codes). However, there are also some callers that pass in revsets not provided by the user. `InputError` is not appropriate in those cases. This patch therefore introduces a wrapper around `scmutil.revrange()` that simply converts the exception type. I put it in `logcmdutil.py` since that seems to be the lowest-level module in the (poorly defined) UI layer. Differential Revision: https://phab.mercurial-scm.org/D11560

phase: avoid a no-op resolution of revset from revnums I was surprised that `scmutil.revrange()` supports integers in the list of revsets. I think it's clearer to not pass a list that's known to contain only integers into the function. Differential Revision: https://phab.mercurial-scm.org/D11559

dirstate: push back the future a bit in the test The future was set to 2021-01-01, we push it by 10 years.

dirstate-item: point out that `merged` is set only with p1_tracked This is currently True, and we will use this fact to simplify the API in the next commit. However, we add this assertion first to validate that this is True in the whole test-suite.

dirstate-item: update the attribute documentation It was very outdated. We are about to change these attribute so we should has well have them documented so that the change get easier to grasp.
