fetch_objs breaks when buffer_sample contains pipe symbol |

[hongwen000]

The following is a sample output. In this output, the correct value of buffer_sample is "eval /home/aaa/miniconda3/bin/conda "shell.fish" "hook" $argv | source\n", however, fetch_objs recognizes the pipe symbol as a delimiter, resulting in an error in the entire parsing process.
