Actually, putting this read in a while loop and feeding 'git
send-email's output into that does fork() a subshell:
$ echo "outside: $BASH_SUBSHELL" |while read line ; do echo "$line
inside: $BASH_SUBSHELL" ; done
outside: 0 inside: 1
I'll look into this :)
My reason for asking is concern about scripts possibly breaking if
someone comes along and wants to "fix" --dump-aliases to also dump
the alias expansions. One possibility is just to punt today and say
that when that feature is needed in the future, then that someone can
add a --verbose option to complement --dump-aliases which would emit
the alias expansions as well. One nice thing about punting at this
point is that we don't (today) have to define a format for the output
of the expansions.
I think we should cross the bridge when we get to it.
However, we could still be nice to that brave soul who might want to
cross it in the future, and since at this point we are interested in
listing only alias names, perhaps we should not appropriate the
broader '--dump-alias' option, but go with the more specific
'--dump-alias-names' instead.
