Subject: PATCH: Improve Mosh completion
Date: Fri, 10 Nov 2017 03:35:04 +0300 [thread overview]
Message-ID: <1510274104.17218.0@smtp.gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 3984 bytes --]
This adds ~/.ssh/config based completion support (_ssh_hosts and
_ssh_users functions and userhost state handling taken without
modifications from ssh completion file), existing code was just wrapped
into _mosh function without modifications (except userhost state
handling mentioned above).
