Bug in `nnfolder-generate-active-file'?

[Thor Kristoffersen]

In the function `nnfolder-generate-active-file' (as of Gnus 5.6.45) we
find the following code

...
(let ((files (directory-files nnfolder-directory))
      file)
...

But if you run Emacs on a SYSV Unix, Gnus will break up nnfolder names
into directory names ("mail.misc" becomes "mail/misc"), so
`directory-files' will search `nnfolder-directory' in vain.  Is this
correct or have I overlooked something?

What is the value of gnus-use-long-file-name ?

Right.  That's the issue that you're running into.  The default value
of this variable differs between operating systems.  Note the last
paragraph of the variable's documentation:

**
`gnus-use-long-file-name' is a variable declared in Lisp.

Value: nil

Documentation:
*Non-nil means that the default name of a file to save articles in is the group name.
If it's nil, the directory form of the group name is used instead.

If this variable is a list, and the list contains the element
`not-score', long file names will not be used for score files; if it
contains the element `not-save', long file names will not be used for
saving; and if it contains the element `not-kill', long file names
will not be used for kill files.

Note that the default for this variable varies according to what system
type you're using.  On `usg-unix-v' and `xenix' this variable defaults
to nil while on all other systems it defaults to t.
**

Just explicitly set this to whichever value you like in your ~/.gnus
file, and things will be the same everywhere.

It was a bug, but now I've documented it, so now it's a feature.
