Description
Personally I was most confused by the description of
fish --debug-categories
and needed to look in the code to figure out it supported comma-separated values in addition to globs. Hopefully this rewording and some examples makes it easier for the next person.I also found it helpful to print out the enabled debug categories. Without this information it's hard to tell immediately that your
--debug-categories
value is working as expected.
