It turns out that my quick hack had some problems, so I ended up
implementing the neater solution after all.

* lib/pipeline.h (struct pipeline): Add ignore_signals member.
* lib/pipeline.c (pipeline_new): Initialise ignore_signals to 1.
(pipeline_join): Set ignore_signals if either input pipeline has
it set.
(pipeline_start): Only ignore SIGINT and SIGQUIT if ignore_signals
is set.
(pipeline_wait): Only restore SIGINT and SIGQUIT if ignore_signals
is set.
* lib/decompress.c (decompress_open, decompress_fdopen): Set
ignore_signals to 0 so that SIGINT and SIGQUIT are not ignored
just because a decompression process is running (Debian bug
#462276).
* docs/NEWS: Document this.
