in reply to "NoNe SuCh" in perl core??

Another little tidbit.

A quick little binary search grep of past perl distributions (god bless the "tools" link on search.cpan.org) indicates that the relevent line from perl.c (my_setenv("NoNe  SuCh", Nullch);) was initially in mg.c, and first appeared in perl5.004_01.

Changes indicates the following changes below involving mg.c, ...unfortunately I don't know enough about perforce to pull out individual diffs and figure out exactly which commit message corrisponds to that line, so I still don't understand what it's for...

    What "tools" link? Where do you grep on past perl distributions? That seems like a useful thing to be able to do!

      Go to a release of perl (or any module, for that matter). For instance, here's perl 5.8.6. Look for the Links part of heading for the release. Check out that last link entitled "Tools". Enjoy.
