[patch] a better description of \c

[Benno Schulenberg]

Hi,

The help text for echo describes the effect of the backslash escape 
\c like this:

$ help echo | grep '\\c'
        \c      suppress trailing newline

But what it actually does is different:

$ echo -e "before \c after \a"
before $

It cancels all characters that come after it.  The printf command 
from coreutils has a nice concise description for it:

$ /usr/bin/printf --help | grep '\\c'
  \c      produce no further output

Attached patch makes bash's builtin echo use the same description.
