[PATCH v3 1/2] commit: reorganise commit hint strings

[Hu Jialun <hujialun@comp.nus.edu.sg>]

Strings of hint messages inserted into editor on interactive commit was
scattered in-line, rendering the code harder to understand at first
glance.

Extract those messages out into separate variables to make the code
outline easier to follow.
