   | 9186      | Adjust the max DESCRIPTION.toolong length to 100           |

   | zmedico   | filter_readonly_variables call out of a subshell since     |
   |           | FreeBSD and prefix users have reported apparent corruption |
   |           | of the PATH environment variable that triggers calls to    |
   |           | the wrong version of sed (one that does not support the -r |
   |           | option). An example of what users have observed: >>>       |
