Small tags inconsistency

Hello,

I noticed that if I manually assign tags to a vm through the web interface, when retrieving the tags (i.e. with pvesh get nodes/<node>/qemu/<vmid>/config), they will be listed as tag1;tag2;tag3, while if I assign them through the command line (tested only at creation), when retrieving them from the same source they will be listed as tag1,tag2,tag3. I assume this is because of what semicolons do in a command line, but it would be nice if they were stored internally in the same format.

The problem is obviously hardly noticeable, and I seriously doubt it will affect anyone (like.. ever), but I was trying to automate some VM documentations and I stumbled upon this.

It does look like there is a bit of inconsistency.
Via GUI: tags: t1;t2;t3
Via 'qm set 9012 --tags "i1 i2"' : tags: i1;i2
Via 'qm create 999 --tags "l1 l2 l3"' : tags: l1 l2 l3
Update 999 via gui: tags: l1;l2;l3;l4

Although, I did not get a comma separator. Perhaps you should supply the CLI you used for that case.

P.S.
root@pve-2:~# qm create 999 --tags "l1,l2,l3"
root@pve-2:~# qm config 999|grep tag
tags: l1,l2,l3
Updated via GUI to add a tag
root@pve-2:~# qm config 999|grep tag
tags: l1;l2;l3;l4

PPS
Code: 
root@pve-2:~# qm set 9012 --tags "l1,l3,l4"
update VM 9012: -tags l1,l3,l4
root@pve-2:~# qm config 9012|grep tag
tags: l1;l3;l4

Yeah, I think we might miss some normalization somewhere in the guest creation code path.
Most API properties that are a list (array) of simple strings (without special characters) are using a common separation mechanism that accepts comma, semicolon or space as separator interchangeably, so for PVE internally this is not a problem, but I can get why one, or their tooling, might be confused here.

Would be great if you could create an enhancement request for this over at https://bugzilla.proxmox.com/

Interesting, so it's actually kind of a "catch-all" system that caused the inconsistency.

@bbgeek17, I would be grateful if you could do it, you already gathered the most valuable info and I don't even have an account on Proxmox's Bugzilla yet.

Thank you for the clarifications!
