mc tree displays irritating bevaviour

[simonthum]

.\mc tree

Expected behavior

Some local tree output aka ls , or useage information.

Actual behavior

An endless loop of the current directotry name, roughly tree view formatted is output to console until I crtlc it.

Steps to reproduce the behavior

.\mc tree

mc --version

PS C:\Users\sthum\repos\experimente\minIO> .\mc --version
mc version RELEASE.2023-12-14T00-37-41Z (commit-id=8da737f8fd63de58dc475bf88eb9e285d206e3ae)
Runtime: go1.21.5 windows/amd64

System information

Win10 dev box, mc being in the current directory.

I realize this is not a likely prod setup, but I just wanted to see whether I get to speed in 5 mins (which worked fine, thanks!).

While the worst scenario for this bug is failing already bad scripts, the behaviour is simply not reassuring of minio quality controls. I am sure this bug is not representative and fairly simple to fix, but it spoils simple evaluation attempts like mine.

Confirmed with mc tree play.

Ends up in a loop requesting

Endless loop in mc tree happens when dir contains no files.
To reproduce, create empty dir:

mc mb myminio/tst/emptydir
mc tree myminio/tst/emptydir

You will see ifiniteloop.
