Issue

When installing an extension using PECL, the user may be prompted to provide configuration input. When running this through Hyper, the user is unable to complete the input form as the return key does not perform the expected operation.

Expected: The user completes the form field, hits return and proceeds to the next step.

Actual: The return key action appends ^M to the input string

Observed output:

$ pecl install amqp

Set the path to librabbitmq install prefix [autodetect] : test^M^M^M^M^M

Reproduce the issue in vanilla Hyper by running pecl install amqp and submitting configuration input when prompted. Trace the terminal input handling for the return key and verify that the form advances without appending ^M to the entered value.
