bug#24785: 24.5; Shell-script indentation after line continuation

[Karl Wette]

In Shell-script mode, indentation after a line continuation seems broken:

aaaaaaaaaaaaaaaaaaaa \
    indents to the correct 4 spaces, but

aaaaaaaaaa aaaaaaaaa \
           indents to the first whitespace in the line

${aaaaaaaaaaa}aaaaa \
              indents to after the closing bracket

( aaaaaaaaa ) && aa \
                     indents to after the line continuation

This seems to be very underisable, and there should at least be an option
of getting back the old behaviour of a fixed indent.

There is: Set `sh-indent-after-continuation' to 'always.

Thanks. Unfortunately this isn't yet an option in my version of Emacs, but
I'll keep it in mind for the future.

For older versions you can use sh-use-smie to nil.
