Fill char without alignment

[OlafvdSpek]

The fill character can be any Unicode code point other than '{' or '}'. The presence of a fill character is signaled by the character following it, which must be one of the alignment options. If the second character of format_spec is not a valid alignment option, then it is assumed that both the fill character and the alignment option are absent.

#include <fmt/core.h>

int main() {
    fmt::print("|{:010}|\n", 0); // |0000000000|
}

'1' isn't a valid alignment option, but the fill character still seems to be taken into account. Are the docs not quite right?
