sr #108708: fix for output of 'alias' command

[Eduardo A . Bustamante López]

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.
