I just figured out how to quantify a problem that's been bugging me. Frequently I'll use the history to call up some previously invoked command and then edit it; when I do this I tend to use the ctrl-key combinations for editing and cursor movement (C-a, C-e, C-f, C-b for movement and C-d to delete) to keep my fingers on the home row.

I noticed that C-d acts strangely when trying to delete past a period character: it does nothing at all. Basically, it gets stuck on the period / dot.

The actual forward-delete key (Fn-delete on my Macbook) works fine on dot.

Steps to repro: at a fish prompt, type a.a, C-a, C-d, C-d, C-d. This should add 3 characters, return to the beginning of the line, then delete all 3 characters. What I see is it deletes the first a and then nothing more; the 2nd and 3rd C-d command do nothing.

I tried to search the bug database and the internet to find reports of similar problems and came up empty, but I wonder if this might be related to #384. I don't, however, see any problems deleting other word-separator characters (/, -, _).

I see this under both OS X an Linux. I'm running a recent development snapshot of fish (42497d9) under both OSes.
