Hi Ian,
Sorry for sending two emails in quick succession, but I just realized
that there is one minor problem with your proposed commit which should
ideally be fixed: the commit log message.
* module/ice-9/command-line.scm (compile-shell-switches): @@ no longer
supports arbitrary expressions, only identifiers.
The commit log should briefly describe the changes made within the
associated patch. The rationale for the changes should be secondary,
and arguably do not belong in the commit log at all.
In this case, your commit log does not describe your changes at all. It
contains only the rationale.
The result is quite misleading, because it suggests that your commit
changed the way '@@' behaves. It would perhaps have been a suitable
commit log for my earlier commit (8210c85), but it is quite
inappropriate for your commit.
Mark
