2010-11-22lineedit: fix tab-completion of filenames with spacesMike Shal
Using ash in busybox git version dea28e1e, tab completion doesn't seem to work properly for filenames that have special characters (such as spaces) in them. For example, with filenames "foo bar" and "foo zap", typing "ls fo<TAB>" correctly expands to "ls foo\ ", but then continuing to type "b<TAB>" will produce "ls foo\ bbar", which is not correct (the 'b' is duplicated).
