## Description

Vim is an open source, command line text editor. Prior to 9.2.0845,
StructMembers() in runtime/autoload/ccomplete.vim constructs and executes a
vimgrep command using an insufficiently escaped typeref: or typename: value
from a tags file, allowing an unterminated collection followed by a command
separator to execute arbitrary Ex and operating-system commands when a user
invokes C omni-completion with CTRL-X CTRL-O on a member access whose type
is resolved from that tags file. This issue is fixed in version 9.2.0845.
