Item Group: Bug => Documentation

Follow-up Comment #2:
This is intended behavior. The docs for the trace option:
https://www.gnu.org/software/make/manual/html_node/Options-Summary.html#index-_002d_002dtrace
say:
> Show tracing information for make execution.
> Using --trace is shorthand for --debug=print,why.
Looking at the --debug option:
https://www.gnu.org/software/make/manual/html_node/Options-Summary.html#index-_002d_002ddebug
You'll see this info:
> m (makefile)
> By default, the above messages are not enabled while trying to remake the
makefiles.
> This option enables messages while rebuilding makefiles, too.
> Note that the ‘all’ option does enable this option.
> This option also enables ‘basic’ messages.
However I see that this documentation is incorrect by using the term "above
messages". What it really means is "other types of output"; e.g., without
this option none of the debug options are enabled while rebuilding makefiles.
So, if you want to get tracing for makefile rebuilds you need to add that
debug option as well.
