It appears that the %c and %u escapes were added some time between 4.3.9 (stock standard Mac OS X Snow Leopard 10.6.7) and 4.3.11 (installed via MacPorts).  Having upgraded to 4.3.11 I can now get the "staged" flag to show up:

15:25 ~project ➤ zstyle ':vcs_info:*' formats '%b/%c/%u'                       ±master
15:28 ~project ➤ vcs_info ; echo $vcs_info_msg_0_                              ±master

15:28 ~project ➤ vcs_info ; echo $vcs_info_msg_0_                             ±master!

So apparently the get-revision style needs to be true in order to get the 'unstaged' changes flag to show up for Mercurial.

But now I'm even more confused since vcs_info's "staged" and "unstaged" changes don't conform to my expectations. I'm expecting that my working copy is in one of three states: "dirty" (signified by '?' above), having "added but uncommitted" changes (see '+' above), or unchanged from VCS. Thus (by my thinking), "unstaged" should conform to "dirty", "staged" should conform to "added but uncommitted" - but it looks like that's not the case.

I have been working through that and other sources. My initial problem getting the %c/%u escapes to do anything was due to user error (using the wrong version of ZSH or at least the vcs_info function).

I'll keep note of that for sure!
