Subject: Fix deleting configuration directories with hidden files.
X-Git-Url: http://git.meshlink.io/?p=meshlink;a=commitdiff_plain;h=74e7a207fa1504872f43e00837106d3e40f6a547

Fix deleting configuration directories with hidden files.

We incorrectly skipped files starting with a dot when deleting directories.
This is a problem on macOS, which might add .DS_Store files.
