factor out strbuf_expand_bad_format()

Browse Source 
Extract a function for reporting placeholders that are not enclosed in a
parenthesis or are unknown.  This reduces the number of strings to
translate and improves consistency across commands.  Call it at the end
of the if/else chain, after exhausting all accepted possibilities.
