ash: shell: Fix clang warnings about "string plus integer"
Upstream commit: Date: Sat, 15 Dec 2018 18:49:31 +0100 shell: Fix clang warnings about "string plus integer" Building with clang results in some warnings about integer values being added to strings. While the code itself is fine and the warnings are indeed harmless, fixing them also makes the semantic more explicit: what it is actually being increased is the address which points to the start of the string in order to skip the initial character when some conditions are met.
