maint: rename .oct_config files to .oct-config In Octave, we generally prefer hyphens over underscores in file names unless underscores are required for other reasons (for example, function names in the scripting language are not allowed to contain hyphens). * .oct-config files renamed from .oct_config: scripts/.oct-config, scripts/audio/.oct-config, scripts/deprecated/.oct-config, scripts/elfun/.oct-config, scripts/general/.oct-config, scripts/geometry/.oct-config, scripts/gui/.oct-config, scripts/help/.oct-config, scripts/image/.oct-config, scripts/io/.oct-config, scripts/java/.oct-config, scripts/legacy/.oct-config, scripts/linear-algebra/.oct-config, scripts/miscellaneous/.oct-config, scripts/ode/.oct-config, scripts/optimization/.oct-config, scripts/path/.oct-config, scripts/pkg/.oct-config, scripts/plot/appearance/.oct-config, scripts/plot/draw/.oct-config, scripts/plot/util/.oct-config, scripts/polynomial/.oct-config, scripts/prefs/.oct-config, scripts/profiler/.oct-config, scripts/set/.oct-config, scripts/signal/.oct-config, scripts/sparse/.oct-config, scripts/specfun/.oct-config, scripts/special-matrix/.oct-config, scripts/statistics/.oct-config, scripts/strings/.oct-config, scripts/testfun/.oct-config, scripts/time/.oct-config, scripts/web/.oct-config. * module.mk files updated: scripts/audio/module.mk, scripts/deprecated/module.mk, scripts/elfun/module.mk, scripts/general/module.mk, scripts/geometry/module.mk, scripts/gui/module.mk, scripts/help/module.mk, scripts/image/module.mk, scripts/io/module.mk, scripts/java/module.mk, scripts/legacy/module.mk, scripts/linear-algebra/module.mk, scripts/miscellaneous/module.mk, scripts/module.mk, scripts/ode/module.mk, scripts/optimization/module.mk, scripts/path/module.mk, scripts/pkg/module.mk, scripts/plot/appearance/module.mk, scripts/plot/draw/module.mk, scripts/plot/util/module.mk, scripts/polynomial/module.mk, scripts/prefs/module.mk, scripts/profiler/module.mk, scripts/set/module.mk, scripts/signal/module.mk, scripts/sparse/module.mk, scripts/specfun/module.mk, scripts/special-matrix/module.mk, scripts/statistics/module.mk, scripts/strings/module.mk, scripts/testfun/module.mk, scripts/time/module.mk, scripts/web/module.mk. * input.cc, load-path.cc: Change .oct_config to .oct-config in functions and doc strings.
