1) style fix (don't arrange local variables)
2) BUGFIX: Previously, if ret was turned 1 for some folder, it
would disable the p-flag for every following folders, which
is not desired.
Instead, the "else if" makes sure that the p-flag-section is
only entered when the initial rmdir succeeds.
3) BUGFIX: Previously, the program would cancel with eprintf if
it failed to remove one folder in the parent-pathname.
This is not desired, as we have other folders pending.
Instead, print a warning for the current failing parent-folder,
set ret to 1 and break off the loop at this point.
This allows to finish the other pending folders without issues.
