using pipes with g_spawn_command_line_sync

[Luka Napotnik <luka napotnik gmail com>]

Hello.

I am unable to run a command with g_spawn_command_line_sync() that uses
pipes. For example "echo \"bla\" | wc -l" gives the exact output as the
command insted "1". Other commands without the pipe execute with no
problem. What's the problem?

Greets,
