Summary:
CommandError happens if there is an unknown command flag, or a required
argument is missing. The old behavior is to print an error message to
stderr, then start the pager with the command help printed to stdout.
There are 2 problems with that approach:
1. When using mosh, a long help text might flush the actual error to out of the
screen. The error message will be missed.
2. When captured in shell scripts, the help text printed to stdout would be
captured, which is almost always undesirable.
The actual motivation of this change is for 2. Zsh themes like bullet-train [1]
uses `hg id -b 2>/dev/null` and we'd like to remove `id -b` support. After that,
the command should not polluate stdout with help text.
