Sorry, that was the behavior with Fish 1,20.1. My apologies.
Fish 1.21.6 seems to freeze only if I try to return to job n when
there is no job n:
fish> jobs
Job Group CPU State Command
0 28475 0% stopped man man
1 28666 0% stopped less hello.txt
fish> fg %2
Send job 2, 'fg %2' to foreground
fish: Could not send job 2 ('fg %2') to foreground
tcsetpgrp: Operation not permitted
[Fish freezes.]
It seems that Fish tries to send the job "fg %2" to the foreground and fails.
On a related note, is there a way to specify a job by name (like
"%man") when the command name is ambiguous (both "man ls" and "man
man" are in the background)? There should be a way to disambiguate
the name, no? Like "fg %'man ls'" or "fg %man ls"?
Also, I'm curious -- why did you decide to make "jobs" print a message
when there are no jobs? I think it should print nothing.
