[docs] [issue14787] pkgutil.walk_packages returns extra modules

[Nick Coghlan]

Nick Coghlan <ncoghlan at gmail.com> added the comment:

At the very least, the pkgutil docs need to state clearly that walk_packages only works properly with sys.path entries, and the constraint feature may not descend into packages correctly if an entry is shadowed by a sys.modules entry or an entry earlier on sys.meta_path or sys.path.
