[GSoC][PATCH 0/3] submodule: fixup to summary-v3

Greetings,

The v3 of 'git submodule summary' port to C is currently in 'next' branch of git/git. Recently, the patch recieved some comments from Peff, Dscho and Kaartic:

    1. The definition of 'print_submodule_summary()' contained two
       unused parameters namely 'missing_src' and 'missing_dst'. Hence,
       I had to eliminate them as covered in the commit a22ffa950f
       a22ffa950f (submodule: eliminate unused parameters from
       print_submodule_summary(), 2020-08-21). Reported by Peff.
       Junio also advised to make the output in case of an unexpected
       file mode a bit more user friendly by outputting an octal instead
       of a decimal.

    2. The function definitions of 'verify_submodule_committish()' and
       'print_submodule_summary()' had wrong styling in terms of the
       asterisk placement. Hence it was fixed in 32934998ee (submodule:
       fix style in function definition, 2020-08-22). Reported by
       Kaartic.

    2. The test script 't7421-submodule-summary-add.sh' failed in
       Windows due to failure of t7421.4. Precisely, the 'test_i18ngrep'
       check failed on Windows since the error message which was being
       grepped was different on Windows; it was designed to work on
       Linux. Therefore, we had to eliminate the grep check in t7421.4
       and replace it with a check to see if there is any error message
       or not using 'test_must_be_empty'. Also, to support this change,
       we had to make some small changes in 'print_submodule_summary()'
       function. The call to verify_submodule_committish()' had to be
       guarded using 'p->status !=D' so that it isn't called when the SM
       directory does not exist, therefore, the error message is not
       displayed. This resulted in 82e0956cd2 (t7421: eliminate 'grep'
       check in t7421.4 for mingw compatibility, 2020-08-22). Reported
       by Dscho.
