Looking into that a bit further, it does seem like my explanation above 
was incorrect.  Here's another attempt to explain why setting 
core.commentChar=auto isn't a problem for this change.

8< -----

Use the configured comment character when generating comments about
branches in a todo list.  Failure to honor this configuration causes a
failure to parse the resulting todo list.

Setting core.commentChar to "auto" will not be honored here, and the
previously configured or default value will be used instead. But, since
the todo list will consist of only generated content, there should not
be any non-comment lines beginning with that character.
