Hello, monks.

I have a strange performance problem using MIME::QuotedPrint.

I have uploaded a file called bad.txt - it is 3054 lines and 116k and is full of 'X's and whitespace.

If I generate a sample twice the size by perl -e 'print ( (("x"x100)."\n") x 3000)' > /tmp/good.txt

then run time perl -MMIME::QuotedPrint -e 'print encode_qp(`cat /tmp/good.txt`)' it runs in 0.7 seconds on my machine.

If I do the same for bad.txt, it takes 14 minutes.

Debugging via printf leads me to a regex in QuotedPrint.pm with a comment This makes things complicated and a regex which is too much for me! Can anyone see what's going on? Many thanks....
