claws-mail/src/mimeview.c
Andrej Kacian d0f52e970e Added working_directory parameter to execute_command_line() 
It gets passed as a first argument to g_spawn_sync/async.
Mostly NULL, since that's what was passed until now, but
bsfilter plugin on Windows needs to change to installation
directory (startup_dir).
