Thanks, but what I was trying to find was a reliable way to know, from
qgit side, when a launched external program failed. This should apply
to git commands of course but also to others, as example StGit or bash
ones (ls, cd, etc..).

So the rule should be general enough. Now the rule is to test for the
presence of any message in stdError _or_  for a special Qt flag set,
that is useful to know if the application crashed or terminated
abruptly.

I think I will stick with that because this error detect framework
should stay command agnostic.
