(2.) Additional Feature... subfolders whose name does not qualify to be a repo

[MichaelDimmitt]

it looks like github allows [A-Za-z0-9_.-], and transforms all other
characters to "-"

if, ... meets a wild character ... ignore completely...
do not delete... instead move to temp and know the path..pwd/
this could cause trouble.

later at the end ... back to its location.
then... git add . and push.
