fasta headers not appended but overwritten

[hkaspersen]

Hello, and thank you for creating Pilon!

I am running Pilon version 1.24, and I noticed that the headers of my improved fasta files didn't contain the original information with "_pilon" appended, but only contained "1_pilon", "2_pilon" etc for all contigs. These are assemblies from Unicycler:

Original header:

1 length=1200471 depth=0.89x

New header:

1_pilon

Is there any way to prevent this? I would very much like to keep the original information.
Thanks in advance!
