vim does incorrect autoindentation in the following example:

[Allison Karlitskaya]

Binary package hint: vim

write this program (formatted as follows) with autoindentation on in vim:

#include <stdio.h>

int
main (void)
{
  printf ("Hello world\n");

  return 0;
}

vim gets the indenting correct.

now go up to the line with "int" on its own. enter insert mode at the start of that line. press enter to insert an additional blank line between #include and int. 'int' now incorrectly indents to the right.

Can't reproduce here...

I can see this:
vim file.c
(then follow the steps in the bug)

The indentation mode is cindent, rather than autoindent. It appears to be due to the code which indents after a #ifdef-style line.

One could modify the value of 'cinkeys' as a workaround (see indent.txt in the vim help), but this would also stop correct indentation after #ifdefs/#define/etc.

[Gary Coady (garycoady)]

This will be fixed when vim is updated to version 7.0 (couldn't reproduce in that version).

[Zygmunt Krynicki (zyga)]

This is the proper behaviour. Try help cinopts to check out why.

[Allison Karlitskaya (desrt)]

True story. 'set cino=t0' fixes this.

Perhaps this should be added to the default config?

[Allison Karlitskaya (desrt)]

(noting of course that this is the new upstream default behaviour...)
