        I wrote a simple shell script using sed to convert \n into newlines and 
other \\(.) to \\\1 and called that script dequote.
When I'm trying to call it nothing happens, when I'm calling $HOME/bin/dequote 
it works. There's no alias called dequote, there's no other dequote in path.
When I rename the script and call it it just works as expected.

This looks like a secret command, that just echos its arguments, as calling 
"dequote xyz" echoes "xyz".

But having a secret alias or command is very evil. What's up here?

        see above

        DonÃ't use secret commands. Any builtin has to be documented on the 
help page.
