Item4777: {SafeEnvPath} deserves a decent default

With some heuristics it should be possible to provide a reasonable default value for $TWiki::cfg{SaveEnvPath} at least for the "positive" cases (Linux). Having yet another parameter which needs to be configured to get rid of the warning is just annoying, especially in cases where $ENV{PATH} has already been secured by a decent web server configuration.

In any case the current value of $ENV{PATH} should be reported in the section for $TWiki::cfg{SaveEnvPath}, but I have no idea whether the current doc-generating mechanism would allow that. And there should be a checkbox "keep server setting". But that's not even "Low", that's "Enhancement"

This pretty old problem apparently has been fixed in the meantime: One can keep the server's setting by just providing an empty path, and configure provides sufficient help for the relevant platforms how to set the variable individually if desired. Instead of looking for the corresponding bugs item I'll just flag this one as "no action required".
