The descriptions for portable_name() and portable_directory_name()
appear to be at odds.

portable_name() : ... && (name is "." or "..", and the first character
not a period or hyphen)

portable_directory_name(): ... && (name is "." or ".." or contains no periods)

Should portable_name() be "... && (name is "." or "..", or contains no
periods) && (first character not a hyphen)"? Maybe I'm missing

Also, in the tut3.cpp tutorial code, there's no mention of the dangers
of using "*it" inside the directory_iterator loop. IIRC, in previous
Filesystem revisions, this would throw if you did not have adequate
permissions to see the file to which "it" refers. Has this changed?
If not, I think that you should either wrap the body of the loop in a
try-catch block, or use one of the non-throwing function overloads,
and indicate to the user what the exception safety concerns are. I
think the tutorial code should exhibit enough robustness that the user
can just cut-and-paste to get the basic code needed to use the
