Looks good.
Ignore the remainder unless you are interested in the recent "make

"make style" wants to format this like so:
static int match_placeholder_arg(const char *to_parse, const char *candidate,
const char **end)
I think I can live with either versions ;-)

"make style" seems to be unhappy to see double blank here, and I
tend to agree.
