Weird brace expansion behavior with multiple commas #3002
Description
The brace expansion in x{,,}y does not work correctly.
Reproduction Steps:
- Run the following command:
echo x{,,}y
Expected behavior:
The output should be: xy xy xy
This is also the output that bash gives.
Observed behaviour:
The observed output: xy x,y
Looks like fish incorrectly thinks that we wrote echo x{,\,}y
Additional information:
