[PATCH 1/3] submodule: clean up subsititions in script

From: Casey Fitzpatrick <kcghost@gmail.com>

'recommend_shallow' and 'jobs' variables do not need quotes (they never contain spaces) and do not require any additional prefix, therefore remove the unnecessary subsitition.

'progress' is a boolean value. Treat it like the other boolean values in the script by using a substitution.
