Jeff KingOur is_pseudoref_syntax() function allows upper-case letters, underscore ("_") and dash ("-"). Our glossary definition is vague on the allowed punctuation, but I don't think we have ever used a pseudoref with anything but an underscore. And the existing open-coded syntax check in refname_is_safe() allows only underscores.
The logic comes from 266b18273a (refs: add ref_type function, 2015-07-31), but I couldn't find any comment on the dash in the commit message or the list discussion. It's used mostly for is_pseudoref(), which further requires that the name either end in "_HEAD" or be one of a specific set of "irregular" pseudorefs.
So I don't think we'd ever see a dash in the real world (you'd need to have "FOO-BAR_HEAD"). Let's tighten this up now so that the function is consistent with (and can be used in) other spots.
