Comment 2 for bug 964785

The complication with this is that "intltool-update -m" needs to understand multiple languages. The changes that probably "broke" this for C were those that improved Python string support (which was very flaky beforehand), especially the triple quoted strings. So, now intltool-update reads this as

"""{quote}{newline}{spaces}"""
_"

and the final bits triggers a "translatable string found" (this is used in .scm [scheme, or at least a variant used in "Dr Geo" if I remember correctly] support which we could consider doing away with).
