Prefix Git Status File Path with particular string

Question

I do git status --short at the root (of the Repository), and it lists the file path relative to the root like as follows:

M NumericalProgramming1Src/FloatingPointNumber.md
M NumericalProgramming1Src/NumericalProgramming.md

I want to prefix all the path with a value stored in a variable: CustomPrefix=My/Path/To/Root/ as follows

M My/Path/To/Root/NumericalProgramming1Src/FloatingPointNumber.md
M My/Path/To/Root/NumericalProgramming1Src/NumericalProgramming.md

How could I achieve this?

NOTE: Sometimes git status has more than one character in the beginning.

This looks for very first space character. Do you mean that space character could not exist? — revo, Nov 12 '18 at 21:38
sometimes there are other characters apart from space like DM or DD or ??, etc — Porcupine, Nov 12 '18 at 22:03
It doesn't matter unless space isn't there. Current accepted answer also assumes there is at least one space character. — revo, Nov 12 '18 at 22:13

With awk you simply call:

custom="/test/"
git status --short | awk -v cp="$custom" '{$2=cp$2}1'

For example, while git status --short yields

M org/languagetool/resource/de/added.txt

The above command yields:

M /test/org/languagetool/resource/de/added.txt

How can we use bash variable `CustomPrefix` inside `awk` command instead of `/custom/prefix/`? I am asking because the string stored in this variable changes value in a `for` loop. – Porcupine Nov 12 '18 at 20:07

I have modified my answer accordingly; First, I set a new shell variable `custom` which I use inside my awk command via `-v cp="$custom"` – F. Knorr Nov 12 '18 at 20:12
