+ Quote a table name so it can be used in "SHOW TABLES LIKE <tabname>"
+ SYNOPSIS
+ quote_for_like
+ name - name of the table
+ buff - quoted name of the table
+
+ DESCRIPTION
+ Quote \, _, ' and % characters
+
+ Note: Because MySQL uses the C escape syntax in strings
+ (for example, '\n' to represent newline), you must double
+ any '\' that you use in your LIKE strings. For example, to
+ search for '\n', specify it as '\\n'. To search for '\', specify
+ it as '\\\\' (the backslashes are stripped once by the parser
+ and another time when the pattern match is done, leaving a
+ single backslash to be matched).
+
+ Example: "t\1" => "t\\\\1"
