Docs: Clarify source_group with same group name can be called multiple time to append lists of files
Clarify in the source_group
doc that it can be called multiple times with same group name to append more files to the same group.
The doc says nothing explicit about the behavior of calling source_group
multiple times with the same group name. It does say that the command "Defines a group", which is unclear: if the group with the same name was already defined in a previous source_group
command, is it an error? If not, do the new files get added to the previous list of files under the same group, or is the previous list of files replaced?
The answer seems to be, I suppose by design, that the new files get added.
