[PATCH v4 0/1] MR8573: cmd: tab completion: Treat most delimiters as literals if user specified quotes.
Fix tab completion for commands like: ``` cd "[2025] Tax Documents" ``` while still allowing tab completion for commands like: ``` copy file1+file2 file3 ``` to work.
Without this change, tab completion for cd "[2025] Tax Documents" yields cd "[2025][2025] Tax Documents". Completed text is inserted into the incorrect location due to the closing ']' which was erroneously interpreted as a delimiter before this change.
-- v4: cmd: tab completion: Treat most delimiters as literals if user specified quotes.
