--eval (was: emacsclient proposal)

[Juri Linkov]

> Uh, -f was a typo.  I really meant --eval in my example.

BTW, a pity that Emacs doesn't provide a short option for the `--eval'
command line argument!

By analogy with `--funcall' that have the corresponding `-f',
the short option for `--eval' and `--execute' would be `-e'.

Even though startup.el currently treats `-e' as a shorthand of `-funcall',
it seems that such use of `-e' is obsolete and we are free to reassign it
to `--eval' and `--execute' because the manual doesn't document it:
