Subject: 28.0.92; strange indentation in shell function
Date: Mon, 21 Mar 2022 15:29:09 +0100

[Message part 1 (text/plain, inline)]

When editing a shell-function with cursor behind "batch \" -- see code 
below -- RET inserts a newline and indents onto a strange big amount.

It inserts 2 TABs followed by 4 spaces so "--eval" is at colon with "-p".

Soo also attached foo1.png. BWT whitespace-mode is hardly readable from 
emacs -Q

------
#!/bin/sh

foo1() { date; time -p emacs -Q -L . --batch \
                               --eval "(message (emacs-version))"
}

foo1

Your message had odd whitespace, but I think we're seeing the same thing:


foo1() { date; time -p emacs -Q -L . --batch \
		    --eval "(message (emacs-version))"
}


And that looks like the correct indentation to me?  That is, we indent
after the "time" on the previous line.

What indentation did you expect to get?

I'd prefer no indentation at all here.

foo1() { date; time -p emacs -Q -L . --batch \
--eval "(message (emacs-version))"
}

Beside: Why indent after "time"? Why not line up with "date"?

foo1() { date; time -p emacs -Q -L . --batch \
         --eval "(message (emacs-version))"
}

I don't think that's a common preference, to put it mildly.

Because date is the previous command.  It lines up all the options after
the command they belong to.  (Although it's debatable that the mode
should know that "time" is one of those special commands that execute
other commands, so --eval should arguably line up after "emacs".)
