However, this has the disadvantage that you have to manually stick a
newline at the end to get a nice block ending. But I suppose you
could tack that on automatically with a .= "\n" or some such.
(Update: I realized after posting that I only tested
with spaces as indentation characters, not tabs, which I never use
anyway. I think the code would work with pure tab
indents, but I haven't tested this. I doubt the code would work with
a mixture of spaces and tabs used as indentation.)
Update: Yes,
return $text =~ s{ ^ \s{0,$dent} }{}xmsgr . "\n";
seems to do it for the automatic newline text block end.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
