Bug #19147 mysqlshow INFORMATION_SCHEMA does not work

Description:
In contrast to the output, when other databases are specified as the 1st and only argument of mysqlshow on the command line client

mysqlshow INFORMATION_SCHEMA

does not display the tables comprised by the specified database.

How to repeat:

C:\>mysqlshow --version
mysqlshow  Ver 9.5 Distrib 5.0.17, for Win32 (ia32)

Suggested fix:
Recognize the argument 'INFORMATION_SCHEMA' as a fully specified (no wildcards) database name and display equivalent to SHOW TABLES FROM INFORMATION_SCHEMA.

Thank you for the bug report.

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:

Patch looks fine to me as well.

Pushed to 5.0.25

Noted in 5.0.25 changelog.

For mysqlshow, if a database name argument contains wildcard
characters (such as `_') but matches a single database name exactly,
treat the name as a literal name. This allows a command such as
mysqlshow information_schema to work without having to escape the
wildcard character.

Merged into 5.1.12

Noted in 5.1.12 changelog.
