Very useful patch for grep :-)

[Stepan Koltsov]

I wrote small, but very useful patch for grep (and I want for U applied it
to grep :-) Alain Magloire advised me to send it here (I hope that anybody
helps me to convince him to apply this patch to grep). (Alain Magloire is
maintainer of gnu grep, if anybody doesn't know).

I added key -D (or --filename-once), that print "-- filename:" instead of "--"
with options such as -C, for example:

W/o using my patch:

address@hidden:/usr/share/vim/vim56/doc]% grep -C3 using *.txt | head -15
autocmd.txt-                                                    *GUIEnter*
autocmd.txt-GUIEnter                    After starting the GUI succesfully, and
after
autocmd.txt-                            opening the window.  It is triggered 
before
autocmd.txt:                            VimEnter when using gvim.  Can be used 
to
autocmd.txt-                            position the window from a .gvimrc 
file:autocmd.txt->   :autocommand GUIEnter * winpos 100 50
autocmd.txt-                                                    *VimEnter*
--
autocmd.txt->    let myfiletypefile = "~/vim/myfiletypes.vim"
autocmd.txt-
autocmd.txt-   Your file will then be sourced after the default FileType 
autocommands have
autocmd.txt:   been installed.  This allows you to overrule any of the 
defaults, by using
autocmd.txt-   ":au!" to remove any existing FileType autocommands for the same
pattern.
autocmd.txt-   Only the autocommand to source the scripts.vim file is given 
later.  This
autocmd.txt-   makes sure that your autocommands in "myfiletypefile" are used 
before
address@hidden:/usr/share/vim/vim56/doc]%

U'll value this if U read this in term. with width ~ 80 cols.
Using my patch:

address@hidden:/usr/share/vim/vim56/doc]% grep -DC3 using *.txt | head -15
-- autocmd.txt:
                                                        *GUIEnter*
GUIEnter                        After starting the GUI succesfully, and after
                                opening the window.  It is triggered before
                                VimEnter when using gvim.  Can be used to
                                position the window from a .gvimrc file:
>       :autocommand GUIEnter * winpos 100 50
                                                        *VimEnter*
-- autocmd.txt:
>    let myfiletypefile = "~/vim/myfiletypes.vim"

   Your file will then be sourced after the default FileType autocommands have
   been installed.  This allows you to overrule any of the defaults, by using
   ":au!" to remove any existing FileType autocommands for the same pattern.
   Only the autocommand to source the scripts.vim file is given later.  This
address@hidden:/usr/share/vim/vim56/doc]%

If I do that writing full path name 
(grep -C3 using /usr/share/vim/vim56/doc/*.txt) it become unable to read
output :-)

If anybody don't like vim, I can write other example :-)

This is very useful patch (sent as attachment).

I'm sorry for my bad English, I don't like to go University to English 
lessons :-)
