When I fixed the long-standing makedir() bugs in January, I had the code call

strtoul(..., 0), which I believed to be safe as all modes specified as ASCII
constants in the nmh code started with a leading zero (signifying octal), which
I did as it would work if internal constants were ever changed to hex.
Unfortunately I was unaware of the "Folder-Protect:" .mh_profile entry, which
mh-profile.man documents as an octal-only constant, with no leading zero
required.  I've changed the strtoul() call to an atooi() call and removed the
misleading leading zeroes on the ASCII octal constants in the code and man
pages.  Also changed the "Folder-Protect:" example in the man page to something
more interesting than a duplication of the default.
