New cbq shell: setting creds for more than 1 password protected bucket without space shows only first one in ouptut of \set

\set -creds travel-sample:pass2,beer-sample:pass2;

output of \set:
cbq> \set;
Query Parameters ::
Parameter name : creds Usernames ["travel-sample"]

Named Parameters ::

User Defined Session Parameters ::

Predefined Session Parameters ::
Parameter name : histfile Value [".cbq_history"]

But if we give a space in between:
cbq> \set -creds travel-sample:pass2, beer-sample:pass2;
cbq> \set;
Query Parameters ::
Parameter name : creds Usernames ["travel-sample" "beer-sample"]

Named Parameters ::

User Defined Session Parameters ::

Predefined Session Parameters ::
Parameter name : histfile Value [".cbq_history"]

It shows correct output.
