URL body pattern, ported from Text_Wiki's Url rule regex: scheme + zero or
more slash-terminated segments + final segment + one terminating character
from [A-Za-z%0-9/?=&~_].
Scheme matching is case-sensitive (lowercase only) on purpose: Text_Wiki's
inline URL regex has no i flag and lists lowercase schemes, so Wikidot does
not auto-link HTTP://…. Shared by the autolink rule and the lexer's bold
marker split.
