Patch Level: 16
Release Status: release
Description:
IMHO shell-expand-line expands some aliases to a different command than
the command executed by the unexpanded alias.
I think that shell-expand-line wrongly removes quotes when expanding
aliases which renders the expanded version unusable under certain
circumstances.
I need a certain awk command but sometimes I need to change it a little
(for example (see below): change the print into print $3). This is why I
configured an alias and when I need to change it I expand it using C-M-e
(shell-expand-line) and edit it by hand. Since the quotes are striped by
the expansion the expanded version is broken.
I was suggested to use a function instead of an alias but this makes it
impossible to expand and edit the command in the cases when I need to
change it.
I think that shell-expand-line should expand to the same command as the
one which is executed when shell-expand-line is not called.
Repeat-By:
$ alias SC='awk '\''!/^#/ {print}'\'''
$ SC # and hit C-M-e
# expands to
$ awk !/^#/ {print}
# since the '' enclosing !/^#/ which are part of the alias are striped
# the awk command wont work.
# I think C-M-e should expand to
$ awk '!/^#/ {print}'
