Description

When using %s, %d, etc the %s part is not highlighted in tree-sitter parser. Without tree-sitter they are highlighted. I thought it would belong better in atom/language-c, but then I checked the scopes, and they are different with tree-sitter and without, so I'm guessing this is a better place. Apologies if it isn't.

Steps to Reproduce

Use escaped characters like %d, %s in format strings.

Expected behavior: The escaped characters should be highlighted differently from the rest of the string

Scope:

source.c
meta.block.c
string.quoted.double.c
constant.other.placeholder.c

Actual behavior: They are not highlighted

Scope:

source.c
string.quoted.double

Reproduces how often: 100%
