Sure, but in a separate patch and ensure blank lines are ignored.

+                               if ($l !~ /^\ {2}/) {
+                                       $wrong_indent = 1;
                                }

The message you used:
+                               WARN("CONFIG_DESCRIPTION",
+                                       "help text is not indented 2 spaces more than the help keyword\n" . $herecurr);

is IMO a bit oddly phrased and could/should test only
the first line after the help keyword and show the help
line using $hereprev.
