Sebastian Spaeth 472476db6f Remove over-verbose debug options
The debug output for dequote, optionsplit is very verbose, outputing
what the functions are called with and what they return. Those functions
are now very old mature and rather simple, so it suffices to output
their return value rather than cluttering out log with too much
uninteresting garbarge.

This makes log files much more readable.
