Here (.+) is greedy and thus will match as much as possible,
including trailing tabs or spaces, thus leaving the [ \t]* with
nothing (which will then do zero repeats).


% Markdown.pl <<< $'Test \n=\n'
<h1>Test </h1>

While it doesn’t matter, I would expect the intended output to be:


And if not, well, then the above regexp could just as well be:

^(.+)\n=+[ \t]*\n+
