Bug: Heredocs are not preserved

[nettnikl]

Hello!
I'm facing an issue in the transition of this DEB File. The installation fails with an syntax error: unexpected end of file.

Details

Looking into the postinst script in the original deb file, you can see there is a heredoc, that is not well preserved in the resulting pkg.tar.zst file. Specifically, the transition to a single script (.INSTALL) add tabulators to all lines of the postinst script, which results in the heredoc delimiter (\nEOF) being destroyed.

Workaround

Manually replace all \tEOF in the .INSTALL file by EOF.
