- add command and variable description field - add fuzzy completion on repeated TAB in minibuffer - remove fuzzy_search variable - add CompletionDef flags: - CF_FILENAME to use `/` as separator - CF_NO_FUZZY to prevent fuzzy matching on second TAB - CF_SPACE_OK to prevent SPC from completing entry - CF_NO_AUTO_SUBMIT to insert current match on ENTER - fix invalid free on CommandDef structures - improve symbol completion in eval-expression - use symbol completion in apropos - fix post increment and decrement evaluation
