Subject: Bug in Dir.glob in 1.8.6 on Windows?

Hi,

I got a bug report for webgen which appeared when the user change from
ruby 1.8.5 to 1.8.6 using the One-Click-Ruby-Installer. Following is
an extract from an IRB session under Windows with ruby 1.8.6:

irb(main):005:0> Dir['src/**/**']
=> ["src/about.de.page", "src/about.page", "src/default.css", "src/
defau
lt.template", "src/images", "src/images/bodybg.gif", "src/images/
boxbg.g
if", "src/images/greypx.gif", "src/images/header.jpg", "src/images/
inner
bg.gif", "src/images/leaves.jpg", "src/images/tabs.gif", "src/
index.de.p
age", "src/index.page", "src/links.de.page", "src/links.page"]
irb(main):006:0> Dir['src/**/**/']
=> ["src/", "src/about.de.page/", "src/about.page/", "src/
default.css/",
 "src/default.template/", "src/images/", "src/images/bodybg.gif/",
"src/
images/boxbg.gif/", "src/images/greypx.gif/", "src/images/
header.jpg/",
"src/images/innerbg.gif/", "src/images/leaves.jpg/", "src/images/
tabs.gi
f/", "src/index.de.page/", "src/index.page/", "src/links.de.page/",
"src
/links.page/"]

Why do all the files get a slash appended and why get files returned
at all? I imagine that the second command should only return
directories... at least this was the behaviour before 1.8.6 - same
session on Windows with Ruby 1.8.5:

irb(main):005:0> Dir['src/**/**']
=> ["src/about.de.page", "src/about.page", "src/default.css", "src/
defau
lt.template", "src/images", "src/index.de.page", "src/index.page",
"src/
links.de.page", "src/links.page", "src/images/bodybg.gif", "src/images/
b
oxbg.gif", "src/images/greypx.gif", "src/images/header.jpg", "src/
images
/innerbg.gif", "src/images/leaves.jpg", "src/images/tabs.gif"]
irb(main):006:0> Dir['src/**/**/']
=> ["src/", "src/images/", "src/images/"]

As you can see, this outputs the correct result, at least in my
understanding.

Has this behaviour already been seen/has anyone an explanation for
this and does anyone know how to only get directories using Dir.[] in
ruby 1.8.6 under Windows?

Thanks for helping!

Best regards,
  Thomas

ps. Also tested this with Ruby 1.8.6 unde Mac OSX and there it works
just fine!
