Comment 145 for bug 1142213

Git commit 2068101234271725def6fe91de4a26543b260cba by Hugo Pereira Da Costa.
Committed on 19/06/2013 at 12:17.
Pushed by hpereiradacosta into branch 'master'.

Re-added use of g_spawn_command_line_sync in place of popen, to execute an external comment.
This effectively reverts commit 51b662b0cd86fd7a960cc2f0c436441d64b2dd44
Rational:
- the failure of g_spawn_command_line_sync was a glib bug 3.6.0, that got fixed since then (3.6.2)
- the use of popen generates unnecessary console when compiled for windows
- the use of popen makes it difficult to redirect stderr, which results in error messages being printed
on screen when the executed command failed (for instance because the relevant application is not
installed.
