annotate src/sysdep.h @ 5524:e05d98bf9644

Style and indentation corrections, behavior.el. 2011-06-19 Aidan Kehoe <kehoea@parhasard.net> * behavior.el (enable-behavior): * behavior.el (disable-behavior): Remove a couple of redundant lambdas here, and remove a cond clause that was never tripped (because nil is a list.) * behavior.el (behavior-menu-filter): Correct some indentation here.
