error: use detailed exit code 10 for command errors Command errors (unknown or ambiguous commands, or bad command arguments or options) are handled in the `dispatch` module. Most other errors are handled in the `scmutil` module. This patch therefore has to duplicate a little bit of code from the `scmutil` module. It's just a few lines, however, so it seems fine to me. It's a pretty common category of errors, so it's important to have them respect `ui.detailed-exit-code`. Differential Revision: https://phab.mercurial-scm.org/D9777
