But is it important to recover the original log data? I don't think
it is. The server should do some form of normalization (I prefer this
term to "munging"), IMHO.
For instance, one could decide that the number of ending newline
characters must be fixed (choose either 0 or 1). I don't think it
makes sense to have a variable number of newline characters (when
this happens, it happens by accident).
Also, is the EOL for log messages always \n on the server, or does it
depend on the platform of the client that submitted the log message?
IMHO, it should always be \n (so that it can be correctly converted
on the client side when displaying the log). But if such a conversion
occurs, this is "munging" too. :)
