The "openstack overcloud update stack -i" command did not handle invalid regular expressions. This caused command termination with an error:
openstack unexpected end of regular expression
This fix detects invalid regular expressions and provides a warning to the user about the invalid value. The command now handles invalid expressions and prompts the user to enter a new value.
jan, can you write the doc text for this one given you did the patch?
