Original-Report: https://savannah.gnu.org/support/index.php?108708
Reporter: Pasha Bolokhov
Alias produces non-reusable output:
dualbus@yaqui:~$ alias -- -x='echo x'
dualbus@yaqui:~$ alias -p
alias -x='echo x'
alias ls='ls --color=auto'
'help alias' claims it's reusable:
alias -p|grep reusable
dualbus@yaqui:~$ help alias|grep reusable
Without arguments, `alias' prints the list of aliases in the reusable
-p Print all defined aliases in a reusable format
The original report also contains the attached patch.

Subject: [PATCH] Fix output for an alias starting with a dash
When an alias name starts with '-' the 'alias' command
now inserts a double-dash to make sure the name in not
treated as an option:
alias -- <name>=<value>
