Current behaviour: Suppose the following alias is defined: ll='ls -la'. Suppose ~/.jshrc contains the instruction: alias ll "ls -l"

$ alias
alias ll="ls -la"
$ source ~/.jshrc
$ alias
alias ll="ls -la"
alias ll="ls-l"

According to POSIX, in the case of a double aliasdefinition, the older alias should be overwritten with the newer one.

Expected behaviour:

$ alias
alias ll="ls -la"
$ source ~/.jshrc
$ alias
alias ll="ls -l"
