Bug#552108: vim-runtime: sh syntax highlighting should default to POSIX.

[Timothy Allen]

Package: vim-nox
Version: 2:7.2.245-2
Severity: wishlist


I'm aware that the issue of Vim's shell-script syntax-highlighting
defaults have been a hot issue on the vim-dev mailing-list, spawning
long and involved threads such as these:

    http://thread.gmane.org/gmane.editors.vim.devel/19923
    http://thread.gmane.org/gmane.editors.vim.devel/19018/focus=19038

In Debian bug 361177, sh.vim learned a g:is_posix configuration value,
and the current sh.vim documentation states:

    If there's no "#! ..." line, and the user hasn't availed
    himself/herself of a default sh.vim syntax setting as just shown,
    then syntax/sh.vim will assume the Bourne shell syntax.  No need to
    quote RFCs or market penetration statistics in error reports, please
    -- just select the default version of the sh your system uses in
    your <.vimrc>.

Reading through the threads above, it seems one of the major reasons
contributing to upstream defaulting to classic Bourne syntax is that
many people use Vim on systems with a classic Bourne /bin/sh for legacy
reasons. This seems quite reasonable, however Debian is not such
a system. I could "just select the default version of sh my system uses
in my .vimrc", but since every Debian user has a POSIX /bin/sh, it makes
sense that the Debian vim package should be configured appropriately
out-of-the-box.

Adding this to $VIMRUNTIME/debian.vim along with the other
Debian-integration customizations should do the trick nicely:

    let g:is_posix = 1
