gnucash-3.904-2020-06-11-git-3.904-20-g5766ae4bc+.setup.exe (Windows):

The following items of gnucash.exe's help screen (same for comparable help screen items of gnucash-cli.exe) are a bit confusing to me.  Clarification would be helpful to other users, too, I believe.

--logto: 
The default location ('/tmp/gnucash.trace' currently shown) should be platform-dependent, since for Windows the location is different than for Unix-like platforms.

--log:
What are admissible module names? (A list could be queried with, eg, an extra help screen ('--help-extra') or alike.)
Can the module name be empty (eg '--log "=info"', see --debug) to probably switch the log level to 'info' for all modules?

--debug:
Is the part of the equivalent command line flag '--log "=info"' really true? (See --log.)

--input-file:
Is 'gnucash --input-file abc.gnucash' equivalent to 'gnucash abc.gnucash' - or does the --input-file serve another purpose?  A clarification would be helpful. 

Thanks,
J.

  --debug                 Enable debugging mode: provide deep detail in the
                          logs.
                          This is equivalent to: --log "=info" --log "qof=info"
                          --log "gnc=info"
  --extra                 Enable extra/development/debugging features.
  --log arg               Log level overrides, of the form
                          "modulename={debug,info,warn,crit,error}"
                          Examples: "--log qof=debug" or "--log
