Parsing formID out of display value doesn't work when FULL contains a '['

[mrudat]

Passing 'SomeEditorID "A FULL name with an unmatched [" [ARMO:DEADBEEF]' to something that expects a FormID results in an error; specifically complaining that the supplied value isn't an integer.

Passing 'SomeEditorID "A FULL name with matched []" [ARMO:DEADBEEF]' to something that expects a FormID works ok.
