If this example is in the man page, then it should be fixed:

for i in *.log ; do
   echo "$i"

Description:
A leading dot in extglob pattern fails to expand as expected.

Repeat-By:
cd $(mktemp -d)
touch .Xdefaults
shopt -s extglob
echo @(.Xdefaults)

but it prints @(.Xdefaults)

works in ksh93 Version JM 93u+ 2011-06-22
