[wplug] Line-by-line input from stdin, from a bash script ?

[Pat Barron]

Does anyone have any favorite methods of doing "line at a time" input 
from stdin, using a bash script?  Is "read" reliable enough to use for 
this?  Will it do antisocial things to me, like trimming trailing 
whitespace from lines it reads?  (Ultimately, what I want is the exact 
input, byte-for-byte, that was read from stdin...). I've only ever used 
it, really, for prompting for stuff interactively, never tried to use it 
from a script.  Is there some other way I'm not aware of?
