It's not very neat, but you could alter indent() to take an optional second argument which is the maximum amount of leading space to trim. eg:
#!/usr/bin/perl
use strict;
print "Content-type: text/plain\n\n";
print "Test\n\n";
sub indent {
my ($text, $cols) = @_;
$cols //= 1000;
$text =~ s/^\s{0,$cols}//gm;
return $text;
}
if (1) {
print indent(<<"END_TEXT", 1);
Here is
some test text
with plenty of space
and an indent here
at the start
END_TEXT
}
exit 0;
Note that you'll need to be careful with tabs v spaces. The value of 1 for $cols here is fine for a tab. You'll see that with that level, the indent on line 4 of the paragraph is preserved.
PS. indent is probably better named outdent since that is effectively what it is doing.

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).
