[pacman-dev] [PATCHv4 5/6] pacsearch: pattern arguments work as for pacman

[Pierre Neidhardt]

Previously only one pattern was allowed.

  $ pacsearch foo bar
Search for packages containing 'foo bar'.

  $ pacman -Ss foo bar
Search for packages containing both 'foo' and 'bar'.

Note that removing the quotes from the call was not enough since
  $ pacsearch 'foo|bar'
would then fail.

Note the use of '--' to indicate the end of option parsing. This way we ensure
that input will always be valid and we need not input checks anymore.
