PATCH: Fix getent completion

[Mikael Magnusson <mikachu@gmail.com>]

getent --help now looks like this:

Supported databases:
ahosts ahostsv4 ahostsv6 aliases ethers group gshadow hosts netgroup
networks passwd protocols rpc services shadow

For bug reporting instructions, please see:
<http://www.gnu.org/software/libc/bugs.html>.

which results in completion like this:
% getent <tab>
===database
\<http://www.gnu.org/software/libc/bugs.html\>.  aliases  hosts          please     services
For                                              bug      instructions,  protocols  shadow
ahosts                                           ethers   netgroup       reporting        
ahostsv4                                         group    networks       rpc              
ahostsv6                                         gshadow  passwd         see:             

Rather than change the -1 to -3, this should still work with old versions that don't have extra lines after the databases output.
