Is this issue reproducible using the latest version of Midnight Commander?

• I confirm the issue is still reproducible with the latest version of Midnight Commander

How to reproduce

1. Run mc displaying the same directory in both panels, on a filesystem with less than 10gb of free space, so that the free space info at the bottom of each panel is measured in megabytes, not gigabytes.
2. Run a command that alters the amount of free space for some megabytes (e.g. copy some large file), either in the current mc session, or in another terminal.

Expected behavior

The free space information under each panel should be updated.

Actual behavior

The free space information is not updated.

It will only be updated when:

• You change the current directory, via cd, or via the quickcd feature, or via the GUI
• You change the other panel's directory via Alt-o

The following actions, which are expected to cause a free space update, also don't have any effect:

• Ctrl-r
• Switching to the other panel
• Switching to the subshell (Ctrl-o) and back
• Execute another command using the CLI
• Execute another action that modifies the free space, using mc copy/move/delete features (F5/F6/F8)

The bug doesn't happen when mc displays a different directory in each panel. I.e. free space is correctly updated after running any command that alters the filesystem, and after performing the other actions listed above.
