segment-nz means non-zero-length segment. That should be pretty clear
when provided the ABNF rules in context. I'll change the segment-nzc
to segment-nz-nc, and path-abs to path-absolute.
segment = *pchar
segment-nz = 1*pchar
segment-nz-nc = 1*( unreserved / pct-encoded / sub-delims / "@" )
; non-zero-length segment without any colon ":"
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
However, I don't want people to figure them out by looking
at the terminal names -- I want them to implement the grammar itself,
which is better defined by reading the ABNF rule than by guessing
on the basis of the names used; the names are short because I am
space-constrained to 68 columns.
