[RFC]rev-parse: rev-parse.h does not exist for rev-parse.c

[Shourya Shukla <shouryashukla.oo@gmail.com>]

Hello all,

I was writing the C code for the summary subcommand of 'git submodule'
when I came across this:

I need to use 'git rev-parse' in the main frontend module_status()
function. Now, instead of creating a string for the 'git rev-parse'
using 'argv_array_pushl()', I thought maybe I could call 'rev-parse.h'
and use the 'cmd_rev_parse()' function directly.

The 'rev-parse.h' file does not exist, only its .c counterpart does. Is
there any reason for this? Would you advise creating a 'rev-parse.h'
file?

Thank you so much in advance for the help and comments :)

Regards,
