CommandPrefix = '.' causes bot to respond to all messages

[ThePoShWolf]

When CommandPrefix is set to '.', it causes the bot to respond to all messages with:

No command found matching [typed message]

Commands prefixed with a period still work though.

Expected Behavior

What should happen is the bot should not respond to any messages except for commands prefixed with a period.

Current Behavior

Currently when CommandPrefix is set to '.' the bot responds to all messages with:

No command found matching [typed message]

Possible Solution

No idea. You mentioned you think that some where

"some message" -match '.'

Is evaluating to $true.

Steps to Reproduce (for bugs)

Here's my bot config:

$botParams = @{
    name = 'snipperbot'
    BotAdmins = @('anthony')
    CommandPrefix = '.'
    LogLevel = 'Verbose'
    PluginDirectory = 'C:\PoshBot\Plugins'
    BackendConfiguration = @{
        Name = 'SlackBackend'
        token = '<removed for privacy>'
    }
}
$botConfig = New-PoshBotConfiguration @botParams

Context

I was simply trying to use a period as the command prefix. Less of a stretch than an exclamation point.

Your Environment

• Module version used: 0.11.0
• Operating System: Windows 10,
• PS version: 5.1.17134.228

Also switching the CommandPrefix to '!' completely resolves the issue.

The mention that "some command" -match "." would always evaluate to true. I think the solution there is to wrap that in a [regex]::escape() and it should handle using . or * or other regex characters as the bot command character.
