[pve-devel] [PATCH common 1/4] pty: introduce read_line() function

[Fiona Ebner <f.ebner@proxmox.com>]

From: Stefan Hrdlicka <s.hrdlicka@proxmox.com>

Originally-by: Stefan Hrdlicka <s.hrdlicka@proxmox.com>
[FE: avoid changes to read_password()
     rename from read_input() to read_line()
     avoid undef warning if there is no input by avoiding chomp then
     print prompt even if not reading from interactive for better log]
