tests: filter control sequences only when interactive This demonstrates that we only write control sequences when interactive.

Only expand abbreviations if cursor is directly at command token On a commandline like "ls arg" (cursor at end) we do not expand abbrevations on enter. OTOH, on "ls " we do expand. This can be frustrating because it means that the two obvious ways to suppress abbrevation expansion (C-Space or post-expansion C-Z) cannot be used to suppress expansion of a command without arguments. (One workaround is "ls #".) Only expand-on-execute if the cursor is at the command name (no space in between). This is a strict improvement for realistic scenarios, because if there is a space, the user has already expressed the intent to not expand the abbreviation. (I hope no one is using recursive abbreviations.) Closes #8423

Fix regression spuriously expanding abbr with cursor outside token Given "abbr foo something", the input sequence foo<space><ctrl-z><space> would re-expand the abbreviation on the second space which is surprising because the cursor is not at or inside the command token. This looks to be a regression from 00432df42 (Trigger abbreviations after inserting process separators, 2024-04-13) Happily, 69583f303 (Allow restricting abbreviations to specific commands (#10452), 2024-04-24) made some changes that mean the bad commit seems no longer necessary. Not sure why it works but I'll take it.

# Or use Control+Space ("bind -k nul") to the same effect.

# Do not expand abbrevation if the cursor is not at the command, even if it's just white space.
# This makes the behavior more consistent with the above two scenarios.
