Minor bug in 4.58.9: check_mail:123 "echo -n" is not portable

[René Berber]

Hi,

As the subject says, the new version has a check_mail with line 123:

  echo -n 'Starting MailScanner...'

the problem is that "echo -n" does not work everywhere, specifically it doesn't
work in Solaris 9, 8, ... with the stock echo, or the built-in Bourne shell echo.

Alternatives are, in order of preference:

1. printf 'Starting MailScanner...'

2. echo 'Starting MailScanner...\c'

The first one is probably portable, the second is what we use in Solaris and
probably doesn't work anywhere else.
