Do you mean something other than this chunk?
An explanation string may be appended to any of the preceding forms of
var(optspec) by enclosing it in brackets, as in `tt(-q[query operation])'.
The tt(verbose) style is used to decide whether the explanation strings
are displayed with the option in a completion listing.
If no bracketed explanation string is given but the tt(auto-description)
style is set and only one argument is described for this var(optspec), the
value of the style is displayed, with any appearance of the sequence
`tt(%d)' in it replaced by the var(message) of the first var(optarg)
that follows the var(optspec); see below.

It did indeed, I just copied that.

The fix looks all right and I've just committed it to both branches:
*Submitted By:* IKEGAMI, Tsutomu (ikegami)
*Date Submitted:* 2003-04-16 09:18
I'm using zsh on Mac OS X, where filenames are encoded with UTF-8.
There, pwd builtin command gives a wrong answer if:
1) used inside of a shell-script,
2) there's no preceding cd command,
3) chase_links option is off,
4) and the script is launched from a 'Kanji' directory.
The 'Kanji' directory means that some characters outside of ASCII set
(0x20-0x7f) are contained in the path.
Pwd command uses internal variable char *pwd for its answer. *Pwd
is initialized in init.c, where PWD environment variable is refered.
PWD environment variable may contain META characters under UTF-8
encoding, but it is used without metafy().
