Mime parser drops lines that start with a hyphen.

The Mime parser drops lines that start with a single hyphen. It considers them as the start of a boundary, and when they don't match it moves on to the next line. It should append the line to the content.

Patch and test coming.

This fix needs to be applied as soon as possible. This problem is corrupting various files, mostly PDFs, received by the SOAP + MTOM.

I had same issue mostly with PDF files and spent a lot of time to figure it out.
Applying proposed solve the issue, at least for one corrupted file, which is now correct.

Any news about merging the related PR ?
