protocol.h: move definition of DEFAULT_GIT_PORT from cache.h
Michael J Gruber noticed that connection via the git:// protocol no
longer worked after a recent header clean-up. This was caused by
funny interaction of few gotchas. First, a necessary definition
#define DEFAULT_GIT_PORT 9418
was made invisible to a place where
const char *port = STR(DEFAULT_GIT_PORT);
was expecting to turn the integer into "9418" with a clever STR()
macro, and ended up stringifying it to
const char *port = "DEFAULT_GIT_PORT";
without giving any chance to compilers to notice such a mistake.
