[bug-grep] Re: [patch #3644] --initial-tab and 3 newly colorized items

[Stepan Kasal]

Hello,

I owed an answer for this patch for a long time; I'm sorry for that.

In short, I this patch (with both --initial-tab and GREP_COLORS features)
will go in.
I also think that the --show*function options should eventually go in.

I thought about it a lot.  I also asked a friend of mine, whose opinion
I value high.  (His comment on -T was that it could be useful for visually
impaired people using Braille terminal.)

With the new colouring features, I understand that if we can colour
matches we should be able to colour other information, too.
I had an idea of config file, where one could specify other strings, not
only "\e[%sm"--but I think it would be an overkill and I like tour solution
now.

Regarding the warning: yes, of course, errors shouldn't be silently ignored.

Regarding the \e[K issue.  I fail to understand it fully, but what would be
``expensive'' on the solution that sgr_end would be \e[m\e[K (in other
words, `cl' would be hardcoded)?

Regards,
