Shouldn't that be equivalent to 'exec', since 'exec' returns the
stdout of the command as result?
man exec(n)
If standard output has not been redirected then the exec command
returns the standard output from the last command in the pipeline.
It seems to me that some info is missing here. Either 'exec' isn't
'exec', or the main program is not tclsh, or lynx isn't plain lynx,
but some wrapper which fiddles with its stdout. Or...
R'
