Hi Stefan,

Returning to the bug list, in case others have opinions on the matter...

But in this case, some users may not want ^M handling, so providing a
hook gives users the choice, no?

> E.g. in this case we want to change shell-command.

I agree that given the command is called 'shell-command' it would make
sense for ^M characters to be handled in shell-like way, i.e., no ^Ms,
in which case perhaps we should provide a spearate command for users who
_don't_ want ^M handling; 'unfiltered-shell-command' or something like
that?

Then again, adding a hook and leaving shell-command as it stands is the
simplest option and has the advantage of not breaking anything, i.e.,
no backward compatibility issues.

Closing Bug#1973, since async-shell-command is now in the trunk.
