Attempting to include quote.h without first including strbuf.h results in warnings:
./quote.h:33:33: warning: ‘struct strbuf’ declared inside parameter list ./quote.h:33:33: warning: its scope is only this definition or declaration, which is probably not what you want ./quote.h:34:34: warning: ‘struct strbuf’ declared inside parameter list ...
Add a toplevel declaration for struct strbuf to avoid this.
While at it, stop including system headers from quote.h. git source files already need to include git-compat-util.h sooner to ensure the appropriate feature test macros are defined.
