file ends with colon open but content isnt read

Edit by @rsese to add more specific repro steps

1. echo "123" > a:
2. Application: Open File (Ctrl+O on Linux)
3. Select the file from step 1

Expect the a: file to open, actual behavior is an empty a titled tab is open.

Seems : is legal though maybe not ideal for a filename on Linux? : is illegal for a filename on Windows and I'm not sure about macOS behavior if it's specifically an illegal character but the behavior was the same on macOS 10.14.6 (except the file open dialog showed a/ in the open dialog).
