Bug #19147: mysqlshow INFORMATION_SCHEMA does not work

Browse Source 
When a wildcard database name is given the mysqlshow, but that wildcard
  matches one database *exactly* (it contains the wildcard character), we
  list the contents of that database instead of just listing the database
  name as matching the wildcard. Probably the most common instance of users
  encountering this behavior would be with "mysqlshow information_schema".

If a wildcard was used, but there was only one row and it's name is an
exact match, we'll assume they really wanted to see the contents of that
database. This is because it is fairly common for database names to
contain the underscore (_), like INFORMATION_SCHEMA.
