Indeed, there's a bug 
 iff both 'echo' is TRUE and the ``file'' that is sourced is not
 a proper file (but e.g. a http:// connection).

It looks like the current code in source() and some of its
helper functions such as getSrcLines()
have not yet been "robustified" to work correctly in such a case.

We (R-core) will look at a patch ASAP.

    Herve> Same with 'verbose=TRUE':

yes, since that automatically uses  echo = TRUE
