Your patch was fine, but your mail client mangled the sole TAB, rendering
it inapplicable via "git am FILE".  The very last line of diff context in
the init.cfg diff should have had a TAB in the brackets after State:,
but instead had a few extra spaces.

  Did you hand edit your patch?
  It does not apply to blobs recorded in its index.

  When you have resolved this problem run "git am --resolved".
  If you would prefer to skip this patch, instead run "git am --skip".
  To restore the original branch and stop patching run "git am --abort".

Applying with git am --ignore-space-change FILE worked around that.

Also, I adjusted this comment to say precisely what we do in that case:

 # Having an unsearchable directory in PATH causes execve to fail with EACCES
 # when applied to an unresolvable program name, contrary to the desired ENOENT.
 # Avoid the problem by rewriting PATH to exclude unsearchable directories.
-# Additionally assure that /sbin and /usr/sbin are included in PATH.
+# Also, if PATH lacks /sbin and/or /usr/sbin, append it/them.
