Bug#671677: vim-tiny: 'filereadable()' in /etc/vim/vimrc does not work

[Rogier]

Package: vim-tiny
Version: 2:7.3.429-2
File: /usr/bin/vim.tiny
Severity: normal

Dear Maintainer,

The function filereadable(), which is used in /etc/vim/vimrc, does not
seem to work. After I changed /etc/vim/vimrc.local, the modified settings
did not take effect, which seems to be caused by the call to filereadable()
in /etc/vim/vimrc failing.

I also ran the following tests:

    prompt $ echo blabla > /tmp/vimrc
    prompt $ vim -u /tmp/vimrc -U NONE -N
    Error detected while processing /tmp/vimrc:
    line    1:
    E492: Not an editor command: blabla
    Press ENTER or type command to continue
    ('ENTER' starts the editor session)

However, after a test using 'filereadable()', the invalid command is skipped:

    prompt $ echo -e 'if filereadable("/tmp/vimrc")\nblabla\nendif' > /tmp/vimrc
    prompt $ vim -u /tmp/vimrc -U NONE -N
    (editor session starts without complaint)

If this is intended behavior (e.g. filereadable() was disabled to
keep vim-tiny small), please add a comment to /etc/vim/vimrc, to explain
this behavior.

Kind regards,

Rogier.
