CLI completion showing ^M after options

[drewnoakes]

Describe the bug

When using CLI completion in Git Bash, ^M characters are displayed after options.

To Reproduce

1. Open Git Bash in Windows Terminal
2. Type dotnet and press Tab a few times
3. Notice ^M in output

Interestingly, this only appears after options, not after file names.

I was going to comment that I cannot reproduce this… but now I see my .bashrc defines _dotnet_bash_complete with | tr -d '\r', which is not part of https://docs.microsoft.com/en-us/dotnet/core/tools/enable-tab-autocomplete#bash. I'm not sure whether I copied that definition from somewhere or added the tr myself.

My .bashrc must've been using an older version of the code at that doc. I updated it and the ^M output is still present.

@KalleOlaviNiemitalo do you also see ^M?

[KalleOlaviNiemitalo]

I don't see ^M with my current .bashrc, but if I redefine _dotnet_bash_complete without the | tr -d '\r', then I see ^M.

Old issue triage: assigning to Chet to update our documentation as that's what needs to be done to solve this on windows system bash.

dotnet/docs#36120 may have fixed that already.
