Wrong help message in 'verdi'

[giovannipizzi]

When running verdi, the command shows an help string.
Now, the error string is wrong: it's just showing the first character for most commands instead of the first line of the docstring as it used to do:

Usage: verdi [--profile=PROFILENAME|-p PROFILENAME] COMMAND [<args>]
