bash_completion: do not use aliased hg if it sources a script (issue6308) I have an alias that sources a script around hg. Mercurial's bash_completion script tries to use this as its main hg binary. But sourcing a wrapper breaks Bash's completion. So this patch disables using the alias as the hg binary if it starts with "source ". Alias resolution was introduced in rev 191ab08e7099 for users with "alias hg='hg --some_opts'". See https://www.mercurial-scm.org/repo/hg/rev/191ab08e7099
