Live documentation doesn't reflect release reality

[skull-squadron]

The documentation says:

SCCACHE_MEMCACHED is a deprecated alias for SCCACHE_MEMCACHED_ENDPOINT for unifying the variable name with other remote storages.

Unfortunately, SCCACHE_MEMCACHED_ENDPOINT has no effect at all in 0.7.7, with or without a spawned server because it's recent churn.

Perhaps development should be straight line on another branch while main is stable and reliable according to what has been released.

Expected behavior

$ SCCACHE_MEMCACHED_ENDPOINT=tcp://.... sccache -s | grep loc
Cache location                  memcached, name: memcached, prefix: /

Actual behavior

$ SCCACHE_MEMCACHED_ENDPOINT=tcp://.... sccache -s | grep loc
Cache location                  Cache location                  Local disk: "...."
$ SCCACHE_MEMCACHED=tcp://.... sccache -s | grep loc
Cache location                  memcached, name: memcached, prefix: /

Environment

• sccache 0.7.7
• rust 1.77.1
