[PATCH v3 01/13] env: Fix documentation for env_get_f()

[Simon Glass]

From: Marek Behún <marek.behun at nic.cz>

This function actually returns:
- the number of bytes written into @buf excluding the terminating
  NULL-byte, if there was enough space in @buf
- the number of bytes written into @buf including the terminating
  NULL-byte, if there wasn't enough space in @buf
- -1 if the variable is not found
