Instead of using "these people", we use "these users".
Note that the "pm-with" single user case has already been updated
to show the user's full name instead of "this person".
Private messages between a user and a bot are not restricted by
the organization's policy setting for sending private messages.
So, for the empty banner text, we set the default title for
a single bot for the "pm-with" narrow.
Group private messages that include a bot are restricted by
this policy setting, so those messages stay the same.
Also, since bot's aren't people, we update the text for valid
"pm-with", "sender" and "group-pm-with" operands to include the
user's full name in the title.
When there are multiple people in the "pm-with" narrow, we still
send a generic "these people" message instead of listing all the
users in the narrow.
Finally, we make the default message end in a period instead of
an exclamation mark.
For narrows that focus on private messages ("is:private", "pm-with",
"group-pm-with"), we want to check the organization private message
policy and set an empty narrow title that matches that policy.
For these narrows with invalid users, we prioritize that message
for the empty narrow title, instead of the private message policy
message.
Fixes#21889.
When "group-pm-with" is the first operator and setting an empty
narrow banner, check that the operand matches a user and set the
title based on whether the user exists or not.
We change the generic message copy while we're at it.
Also, show login_to_access modal when a spectator tries to access
a stream that either does not exist is is not web-public.
Removed existing empty narrow divs from app/home.html and created
a new javascript module to dynamically load empty narrow messages
using handlebar template.
Fixes#18797
The default label for empty narrows depends on whether it's a
stream/topic narrow or a PMs narrow.
We leave some default text in compose.hbs for reply label
because it take some time for the js to display the
correct label.
This is a mostly verbatim extraction.
I re-phrased one line of code to work around a lint
false alarm. (Look for `preamble` in the diff.)
There are about 8 lines missing coverage here, so
the new module might be a good candidate to get
100% line coverage on.
Before this change, you would need to remove 74
edges from our dependency graph to make it
acyclic. Now it's 72.
