[pve-devel] [PATCH http-server] fix regression in api/html (bootstrap) viewer

[Dominik Csapak <d.csapak@proxmox.com>]

recent versions of URI::Escape seem to handle the 'unsafe characters'
parameter differently than before, enforcing what is documented:

 The set is specified as a string that can be used in a regular
 expression character class (between [ ]).

so the leading/trailing [] were never supposed to be there.
