This is actually a bug in the lexer. Debian fields names are indeed allowed to
have all kind of wired characters :
"The field name is composed of US-ASCII characters excluding control
characters, space, and colon (i.e., characters in the ranges 33-57 and 59-126,
inclusive). Field names must not begin with the comment character, #, nor with
the hyphen character, -. "
I'll fix this in the next release.
