Package: dash
Version: 0.5.12-6
Severity: normal

Dear Maintainer,

I found that 'jobs' in dash is silent when stdout is a pipe:

# dash -c 'sleep 1&sleep 1&jobs|wc -l'
0

afaics, this is not documented behaviour, and other utilities (kill, alias) seem
to work fine.

bash does allow the output of jobs to be parsed:

# bash -c 'sleep 1&sleep 1&jobs|wc -l'
2

I think the bash behaviour is more useful for shell programming, and
probably correct, as the sus does not seem to indicate that jobs should
have no output in this case.
