Cannot invoke task with underscore in method name

[dax-westerman]

Version: 2.2.1

Use Case

Using the example tasks.py...

from invoke.tasks import task


@task
def show_help(c):
    """Show available tasks."""
    print("Available tasks:")
    
@task
def showhelp(c):
    """Show available tasks."""
    print("Available tasks:")

Calling showhelp...

invoke showhelp

prints

Available tasks:

however, calling 'show_help`...

invoke show_help

results in

No idea what 'show_help' is!

hi! You can see available tasks/commands by

inv -l

and maybe you need call it like

inv show-help
