[Bug 1576583] [NEW] vim paste option bracks expandtab option

[Oliver Mueller]

Public bug reported:

i am using ubuntu xenial.

when I use vim options at the end of a file like the following:

# vim: syntax=yaml ts=2 sw=2 et sr softtabstop=2 autoindent paste

it should convert an entered tab into spaces (pressing tab should result
into 2 spaces). in the past it actually did. currently it does not
anymore. the problem here seems to be the last option "paste". if i
leave out the paste options the expandtab (et) option works again. the
paste option should not have any effect on the expandtab option though.


steps to reproduce:

- create a file with "# vim: syntax=yaml ts=2 sw=2 et sr softtabstop=2 autoindent paste" at the end of the file. 
- save it
- reopen it with vim
- in insert mode: press tab key
- the tab should have been converted into 2 spaces (but it doesn't)
- remove the paste option  "# vim: syntax=yaml ts=2 sw=2 et sr softtabstop=2 autoindent"
- save it
- reopen it with vim
- in insert mode: press tab key again
- now the tab is converted into 2 spaces
