A commit messages that answers the "what?" and "how?" questions (as
opposed to "why?") is always suspicious: doesn't the message belong
elsewhere?
Here, you have a nice user documentation for command-line options, and
the actual user doc is much poorer:

We're just setting a convention to use ${var} in string interpolation
(Celestin's perlcritic patch series), so better do it right now ;-).
Did you try "make perlcritic" on your code?

I got hit again by the HTTPS certificate validation failure. It would
make sense to have a more detailed error message, including the URL,
because having the same error:
You need to create Accueil before previewing it at
/home/moy/local/usr-wheezy/libexec/git-core/git-mw line 182.
for any kind of HTTP failure is a painful. Doesn't "get" return an HTTP
code? If so, your message would make sense for 404 errors, but not for
the others.

Unfortunately, this doesn't seem standard. It doesn't work on
https://ensiwiki.ensimag.fr/index.php/Accueil at least (which is my main
use-case :-( ).
At least, you should check $mw_content_text and have a nice error
message here. As much as possible, you should allow a way to solve it
(make the lookup configurable in .git/config, or allow the user to
specify an arbitrary HTML template to plug onto, or display the raw,
incomplete, HTML).
I replaced 'mw-content-text' with 'bodyContent' and it worked.
Then I got
Wide character in print at /usr/lib/perl/5.14/IO/Handle.pm line 159.
but the file was generated. There are encoding problems: the title says
"Le Wiki des étudiants et enseignants" (it should be a É).
I guess you fed the API with an improper encoding (double UTF-8
encoding, or UTF-8 announced as latin-1 or so), and the API returned you
some hard-coded, badly encoded, rendered HTML.

Lower-case help and preview.
