The leading path-token run WITH separators preserved (V1). Same stopping
rules as pathresolve's run (V2/V3), so the two stay comparable: a slash-
joined word expands to several slash-separated tokens; a space-separated
word is one space token. Stops at the first =/group/string/var word, and
at any word carrying a non-BARE_WORD segment (a variable segment truncates
the run before the verb).
