Actual behaviour:
t1% command -pv zsh
zsh: command not found: -pv

Expected behaviour:
Look for a 'zsh' executable in the default $PATH and print its path.
(i.e., print '/usr/local/bin/zsh'.)

Environment:
t1% zsh -f
t1% echo $ZSH_VERSION
4.3.10

Mikael Magnusson reported on IRC that he can reproduce that locally,
using a more recent zsh.

Looking into the cause, I guess that it's due to this bit of argument
parsing in ./Src/exec.c:2433:

[[[
	    if ((cflags & BINF_COMMAND) && nextnode(firstnode(args))) {
		/* check for options to command builtin */
		char *next = (char *) getdata(nextnode(firstnode(args)));
		char *cmdopt;
		if (next && *next == '-' && strlen(next) == 2 &&
		        (cmdopt = strchr("pvV", next[1])))
		{
		    if (*cmdopt == 'p') {
]]]

I've looked into converting that parsing to a while() loop (as used by
other if() blocks in the vicinity), but haven't got a working patch yet
and didn't want to delay this email until I did.
