+Subject: [PATCH] build: Fix `USER_DIR_MODE` value in config.h
+
+meson defines `USER_DIR_MODE` with a raw octal value to be used as
+the default permissions when creating the user's configuration
+directory.
+
+However, meson does not support raw octal values[0], so the define
+misses the initial `0` value. Due to this, the directory is created
+with wrong permissions.
+
+This has been changed to use the octal value as a string in meson,
+so the definition has the proper value.
+
+Fixes #49
