Ok, confirming it now, it also happens with the latest git revision.

Sorry I forgot to tell there need to be a space before and after the
location where the cursor is:
$ ls a

Bug#622383: bash-completion: completion only works from left to right: error : bash: $index: substring expression < 0
Package: bash-completion Version: 1:1.3-2 Severity: wishlist Typing : $ ls a then moving the cursor between 'ls' and 'a' and pressing leads to: bash: $index: substring expression < 0 Thus completion only works right to the last character in a command. Is a fix at reach ? Or is it by design ? I could spend some time on this issue though I have not looked into it since bash 3.0 so I bet most of what I know is obsolete. A clue would be welcomed.
