Subject: [PATCH] make config-loading debug messages more explicit

It was never clear in debug messages that the cwd is searched
for config files.  This adjusts various debug messages during
config-file loading to make things more clear:

The following debug messages were added:
* specify search-path at start of load-config routine
* on success, full path of loaded config files
* always note when config files are not found
