Dear Z-Shell developers,
I want to make you aware of the following issue with autocorrection I ran
autocorrection suggested rm for typing mr without typing "y"
Axel analysed this below a bit further an indeed, if I press the space bar, I
ms@merkaba:~> cd /tmp
ms@merkaba:/tmp> LANG=C mr test
zsh: correct 'mr' to 'rm' [nyae]?
rm: cannot remove 'test': No such file or directory
So two fixes to consider:
1) Don´t confirm on space, as thats to easy to trigger accidentally. :)
2) Don´t autocorrect to dangerous commands like "rm". Could be a bit
challenging to make a list of commands which are dangerous and can easily
trigger unwanted actions. "rm" would IMO definately be one of this, while with
"dd" it would be harder to trigger an unwanted action by accident due to
Axel made me aware that I tell Z-Shell to ignore dangerous commands with
CORRECT_IGNORE=rm, but I think it would be good to reconsider the standard

Yikes! Space bar to confirm? And correction to "rm".
Actually what I tried to type was "mv". I obviously wanted to move the file.
But I accidentelly typed "mr". And then, yes, likely the space bar.
I think this deserves a fix in the software :)
