Re: Shell-script[bash] indention broken (or fixed?)

[Richard Stallman]

    Until recently the behavior of Shell-script[bash] mode was to
    not indent the second of the following two lines when tab was hit:

    export VARIABLE=/path/to/here\
    :/path/to/there

    Now it indents it like this:

    export VARIABLE=/path/to/here\
        :/path/to/there

I loaded a version of sh-script.el from September and it gave the
latter result.  So this is not, I believe, the result of a recent
change.

The reason for this behavior seems to be that
sh-indent-for-continuation is +.  Should it be 0?

I am surprised by the existence of sh-indent-for-continuation.
In shell syntax, are spaces after backslash-newline ignored?
I did an experiment and they do not seem to be ignored.
That being so, isn't it simply an error to reindent the
continuation line?
