[patch] added ":e ~user<Tab>" completion

[Dominique Pellé]

Hi

Attached patch fixes the following item in in ":help todo":

===========================================================
":e ~br<Tab>" does not complete to ":e /home/bram/". Would need to use
getpwent() to find all the matches.
===========================================================

Here are 2 examples, assuming that /etc/passwd contains 3 users
names: bill, bob, bram:

Example #1: completion in Ex command

:e ~b<Tab>
... possible completions: bob bill bram

:e ~bi<Tab>
... completes to :e ~bill

:e ~bill<Tab>
... substitute home path :e /home/bill/ (as before patch)


Example #2: user completion in :command

:command! -nargs=* -complete=users Foo

:Foo b<Tab>
... possible completions: bob bill bram

It is implemented for systems supporting getpwent().
configure script checks whether getpwent() is available.
I only tested it on Linux.

Sorry. I noticed an inconsistency in my patch
between ":help command-complete" which
indicated the option "-complete=user" and
the code which expected "-complete users".

I fixed it in this new updated attached patch.

Here is yet another update of the patch.
Previous patch broke completion when
typing ":e ~user/dir<Tab>"

It is be fixed in this updated patch.
Sorry for the noise :-(

My previous patch was missing src/vim.h and src/auto/configure.
So here is yet another update of the patch.

Hello, Dominique:

May I point out that old C compilers (ie. those that conform to K&R
style C) error-out on declarations which follow compilable code. In
particular,
int match_user(name)
char_u* name;
{
init_users();
int i;
...

will not compile with them. All that's needed is to push "init_users()"
to after the initial block of declarations.

Thanks for spotting it. Here is another update to the
patch with a few other minor changes.

Sounds good. I'll add it to the todo list.
