Describe the bug

When running commands that require interactive input in the Windows Git Bash terminal (installed using the Windows Git installer), there is an error:

$ gh pr create
Creating pull request for [...] into master in [...]
? Title could not collect title and/or body: could not prompt: Incorrect function.

Versions:

$ git --version
git version 2.25.0.windows.1

$ gh --version
gh version 0.5.4 (2020-02-04)
https://github.com/cli/cli/releases/tag/v0.5.4

Steps to reproduce the behavior

1. Install Git and GitHub CLI on Windows
2. Open Git Bash, and cd into a repo
3. Run gh pr create

Expected vs actual behavior

Expectation is the interactive UI to create a PR, instead there is an error message:

? Title could not collect title and/or body: could not prompt: Incorrect function.
