`string replace` not working with mutlilines variable.
So split per line first.
* functions/__fish_print_hostnames: remove quotes at `split '\n'`
"\n with quotes" will cause `string split` weird issues.

Fix `$contents` issues together
Since the url is inside a AngularJS markup {{url}}, it's better to use **ng-href**.
From [AngularJS Documentation](https://docs.angularjs.org/api/ng/directive/ngHref):
<br>
"Using AngularJS markup like {{hash}} in an href attribute will make the link go to the wrong URL if the user clicks it before AngularJS has a chance to replace the {{hash}} markup with its value. Until AngularJS replaces the markup the link will be broken and will most likely return a 404 error. The ngHref directive solves this problem."
The `--entire` would enable output even though the `--quiet` should
have silenced it. These two don't make any sense together so print an
error, because the user could have just left off the `-q`.
We used to just check for the presence of "--" on the command line to
make judgements about which completions to suggest. Now, even if "--" is
present, we can still make different suggestions by taking the cursor's
position into account.
If "--" is present in the command line, it's usually safe to assume that
the user is going to want to complete a file tracked by git so let's
only suggest branches if "--" isn't present.
When there is already a "src:", we assume that it is a valid ref and
just complete "dst". This allows completion of dest if src is e.g. a
commit SHA (completing all possible refs would probably impact
performance).
See issue #3035.
This spewed errors because the `math` invocation got no second
operand:
Testing file checks/sigint.fish ... math: Error: Too few arguments
'1571487730 -'
but only if the `date` didn't do milliseconds, which is the case on
FreeBSD and NetBSD.
(also force the variable to be global - we don't want to have a
universal causing trouble here)
sys/sysctl.h is deprecated on glibc, so it leads to warnings.
According to fa4ec55c96, it was included for KERN_PROCARGS2 for
process expansion, but process expansion is gone, so it's unused now.
(there is another use of it in common.cpp, but that's only on FreeBSD)
Also 1f06e5f0b9 only included
tokenizer.h (present since the initial commit) if KERN_PROCARGS2
wasn't available, so it can't have been important.
This builds and passes the tests on:
- Archlinux, with glibc 2.30
- Alpine, with musl
- FreeBSD
- NetBSD
Universal exported variables (created by `set -xU`) used to show up
both as universal and global variable in child instances of fish.
As a result, when changing an exported universal variable, the
new value would only be visible after a new login (or deleting the
variable from global scope in each fish instance).
Additionally, something like `set -xU EDITOR vim -g` would be imported
into the global scope as a single word resulting in failures to
execute $EDITOR in fish.
We cannot simply give precedence to universal variables, because
another process might have exported the same variable. Instead, we
only skip importing a variable when it is equivalent to an exported
universal variable with the same name. We compare their values after
joining with spaces, hence skipping those imports does not change the
environment fish passes to its children. Only the representation in
fish is changed from `"vim -g"` to `vim -g`.
Closes#5258.
This eliminates the issue #5348 for universal variables.
