I agree that it looks like the correct thing to do, however, I'm always concerned of unintended, undesired side-effects that these changes could have. Particularly for this additional change [1], there has been some discussion around it in the past [2], and, more specifically, Ville Skyttä mentioned what could be the side-effects when someone adds `set show-all-if-ambiguous on' to ~/.inputrc [3]. I gave it a try, and here's what it looks like. $ ls /tmp/test/[ENTER] bla ble blee 1) bash-completion 2.8-3 + `set show-all-if-ambiguous off' in ~/.inputrc $ ls /tmp/test/*[TAB][TAB][TAB][...] (no output) 2) bash-completion 2.8-3 + `set show-all-if-ambiguous on' in ~/.inputrc $ ls /tmp/test/*[TAB][TAB][TAB][...] (no output) Same behaviour on both cases. 3) bash-completion 2.8-3 + additional change [1] + `set show-all-if-ambiguous off' in ~/.inputrc $ ls /tmp/test/* bla ble blee $ ls /tmp/test/* (this is the behaviour you want, I guess) 4) bash-completion 2.8-3 + additional change [1] + `set show-all-if-ambiguous on' in ~/.inputrc $ ls /tmp/test/* /tmp/test/bla /tmp/test/ble /tmp/test/blee $ ls /tmp/test/bl (notice that `*' was expanded to `bl' (common part of the options)) There's a difference in behaviour depending on the setting of `show-all-if-ambiguous'. This inconsistency looks weird to me.
