It is said in the readme that exclamation mark denotes conflicted files. However, it also appears when there is an untracked file in working dir. Is it by design?
Ah... there are actually two different exclamation marks: [master|MERGE +1 ~0 -0 !3 | +1 ~0 -0 !3 !].
[master|MERGE +1 ~0 -0 !3 | +1 ~0 -0 !3 !]
The !3 means there are three unresolved merge conflicts; the trailing !, as you noted, means there are untracked files. I honestly don't recall why the latter is included, since a +1 in the working directory section means the same thing.
If you don't like the latter ! you can change set $GitPromptSettings.UntrackedText = '' in your profile after posh-git loads.
$GitPromptSettings.UntrackedText = ''

Thanks for the explanation, updated the readme.
