[PATCH 0 of 3] record: use only one keystroke for 'y' or 'n' when recording a patch

[Kirill Smelkov]

I'm a former Darcs user, and I record patches often.

It seems to be more convenient to just press one of two keys ('y' or 'n')
instead of constanly moving my fingers to 'Enter'.

This mimics 'darcs record' behaviour.
