listing aliases

[Andrew Basterfield]

Hi

I've written an alias that saves the current shell's aliases to ~/.shrc

when you list aliases zsh and ksh don't prepend the word alias to
every line

ksh$ alias
l.='ls -d .*'
ll='ls -l'
ll.='ls -ld .*'
lla='ls -la'
ls='ls --color=auto'

bash$ alias
alias l.='ls -d .*'
alias ll='ls -l'
alias ll.='ls -ld .*'
alias lla='ls -la'
alias ls='ls --color=auto'

Here is my patch to drop the initial alias string when the shell is in
posix mode, thus not breaking stuff that expects the default behaviour.

POSIX says 'alias' should work like Korn 'alias', in my interpretation.

Is this a sensible suggestion or Not Clever?
