bash file regression in 5.77.0

Unfortunately with commit 9f363cac bash file syntax highlighting broke in several ways. The commit is not easily revertable.

• && and || cause the following closing } bracket to be error highlighted (red, underlined)
• Comments within array ( ) blocks are not highlighted but in regular text color

For reference, take this file e.g.: https://gitweb.gentoo.org/proj/kde.git/tree/kde-apps/umbrello/umbrello-20.12.0.ebuild
