bug#51426: 29.0.50; [PATCH] Should 'comint-term-environment' be connection-aware? |

`comint-term-environment' consults `system-uses-terminfo' to determine
how to set environment variables to indicate comint's terminal
capabilities. However, `system-uses-terminfo' describes whether the host
system running Emacs uses terminfo, not whether the remote system uses
it. Similarly for `comint-terminfo-terminal'.
If `comint-term-environment' were aware of connection-local variables,
it would be possible to create a connection-local profile to configure
this for remote hosts, e.g.:
(connection-local-set-profile-variables
'remote-terminfo
'((system-uses-terminfo . t)
(comint-terminfo-terminal . "dumb-emacs-ansi")))
(connection-local-set-profiles
'(:application tramp :machine "foo")
'remote-terminfo))
(Note: "dumb-emacs-ansi" comes from the ncurses-term package[1] in
Debian, and should be a good value to represent comint's capabilities.)
This lets the user pass a terminfo-friendly value for TERM to the remote
system, even if the local system doesn't use terminfo. Then programs on
the remote system can consult terminfo to their hearts' content.
I've attached a patch that does this, assuming the reasoning above makes
sense. Perhaps it also warrants an entry in NEWS? I wasn't sure...
