This patch uses printbuf_indent_add_nextline() to set a consistent
indentation level for error messages of invalid compression.

In my previous patch [1], the newline is added by using '\n' in
the argument of prt_str(). This patch replaces '\n' with prt_newline()
to make indentation level work correctly.

You can just change this to prt_printf() or prt_str_indented(), that'll
interpret the \n correctly

This patch uses printbuf_indent_add_nextline() to set a consistent
indentation level for error messages of invalid compression.

In my previous patch [1], the newline is added by using '\n' in
the argument of prt_str(). This patch replaces prt_str() with
prt_printf() to make indentation level work correctly.
