[Libguestfs] [libnbd PATCH 11/23] generator/C: print_trace_enter: break "enter" to a common new line
Going forward, we'd like to wrap long string literals. The recently
introduced "pr_wrap_cstr" function may only be called right after the
opening quote of the string literal has been produced. In the
"print_trace_enter" function, we start a long string literal with
"enter:"; however, because we either pass the literal to debug() or
debug_direct(), this "enter:" is spelled out twice. Factor "enter:"
out to
a common line, also ensuring that we'll have as much room for wrapping as
possible.
