Shigio> You mean blanks are annoying for you too?

Yes, blanks are annoying since, as you say, many unix tools do
not handle them gracefully.

Most of the other people on the project use (non-unix) tools that
can handle blanks in filenames just fine.  Renaming files in this
case is a very big deal.

I assume here you mean one sort with 3 keys 1,3,2 as above.

I think this would do it for keys 1,3, but not for key 2
(linenum).  Assumes all filenames wrapped by '"'.  I

    $ sort -t '"' -k 1,1 -k 2,2

But if the input could be changed to look like this:

        (1)     (2)             (3)
        +----------------------------------------------------------
        |main^   32^             ./src/m in.c^      main(argc, argv)
        |main^    22^            ./a b/f u n c.c^   main(argc, argv)
        |func^     5^            ./abc/func.c^      func()
        |func2^   10^            ./abc/func.c^      func2()

then this command should do it:

    $ sort -b -t '^' -k 1,1 -k 3,3 -k 2,2n

The '^' is field separator.  '-b' says to ignore *leading* blanks
(left in for readability, but could be removed).
