Bugfix (introduced: Postfix 3.2) extension propagation was
broken with "recipient_delimiter = .". This change reverts
a change that was trying to be too clever. Files:
global/mail_adr_crunch.c, global/mail_addr_crunch.ref.

Safety: restore sanity checks for dynamically-specified
width and precision in format strings (%*, %.*, and %*.*).
These checks were lost with the Postfix 3.2.2 rewrite of
the vbuf_print formatter. File: vbuf_print.c.

Bugfix (introduced: Postfix 3.2): panic in the postqueue
command after output write error while listing the queue.
This change restores a write error check that was lost with
the Postfix 3.2.2 rewrite of the vbuf_print formatter.
Problem reported by Andreas Schulze. File: util/vbuf_print.c.
