[BusyBox] [PATCH] ASH's read bugs

[Paul Fox]

i've committed the patch from bug 242 to svn, which independently
(of this mail and bug 348) addressed the '-t timeout" bugs, and
added "-n nchars" functionality.  based on bug 348 and this mail,
i also added "-s", for silent reads.

 > There is some bugs in ASH's read. I've fixed those that I found and
 > added a new feature. Here they are:
 > 
 > - Timeout:
 >   - The timeout option counts only the first char: it will stop counting
 >     the time after you press the first key;
 > 
 >   - When the timeout option is used, the first char cannot be erased and
 >     is handled wrongly if it is a backslash and/or with IFS environment
 >     variable;
 > 
 >   - Some special characters, when in the first field, cannot be shown or
 >     are treated wrong;
 > 
 >   - The exit code is wrong and the environment variable is empty when
 >     the timeout is expired;
 > 
 > - Silent:
 > 
 >   - I added a `silent' feature: when the -s argument is provided, the
 >     characters are not echoed;
 > 
 > The comparisons I made was using `bash' and `zsh'. The patch is
 > attached.
