Wrong preview when current selection is a directory symlink.

[occivink]

I swear I don't have that many symlinks.

Anyway, when the current selection is on a directory symlink, it will display in the preview pane the content of the last previewed directory.

Example:

$ tree
.
├── bar/
│   ├── bar1
│   ├── bar2
│   └── bar3
├── foo/
│   ├── foo1
│   ├── foo2
│   └── foo3
└── zab -> /home/occivink/tmp/bar/

If you start lf in such a directory and press down twice, it will show

foo1
foo2
foo3

in the preview pane. If you then go left and right, it will show

bar
foo
zab

You get the idea.

Thanks for the detailed bug report @occivink . This is likely the same issue as #24. It seems that lf does not preview links to directories. Previews are buffered for performance reason and since it doesn't update correctly it shows you the previous content. Also since they are not initialized it crashes when the first selection is a link to a directory. Probably a simple issue but it sounds quite annoying. I will try to push a fix as soon as possible, hopefully before tomorrow. Meanwhile if anyone wants to handle this, maybe also initialize the buffers somehow so things won't be so fragile.

Ah yes that makes sense, I can't believe I didn't make the link between the two cases.

I guess this is somewhat related to #20 as well. This broke after the buffering thing, right? I remember it working in the past.

[gokcehan]

Yes, I think so @KenjiTakahashi

@occivink With the latest commit we're handling the directory symlinks correctly. Closing this issue now. Feel free to open again if you have any more problems after you update to the latest version.
