shell: Fix clang warnings about "string plus integer"
Building with clang results in some warnings about integer values being added to strings: ----------------------------------------------------------------------- eval.c:1138:13: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int] p = " %s" + (1 - sep); ~~~~~~^~~~~~~~~~~ eval.c:1138:13: note: use array indexing to silence this warning p = " %s" + (1 - sep); ^ & [ ] 1 warning generated. ... jobs.c:1424:16: warning: adding 'int' to a string does not append to the string [-Wstring-plus-int] str = "\"}" + !(quoted & 1); ~~~~~~^~~~~~~~~~~~~~~ jobs.c:1424:16: note: use array indexing to silence this warning str = "\"}" + !(quoted & 1); ^ & [ ] 1 warning generated. ----------------------------------------------------------------------- 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.
