Hi Simon, Tom,

env_get_char() is a relic from the past when env was read char-by-char
from underlying device. Currently it only accesses in-memory arrays.
We can remove it and access the arrays directly. This simplifies the old
code of env_get_f().


Marek Behún (10):
  env: Drop env_get_char_spec() and old, unused .get_char()
  examples: api: glue: Remove comment that does not apply anymore
  env: Change env_match() to static and remove from header
  env: Don't match empty variable name in env_match()
  env: Check for terminating null-byte in env_match()
  env: Inline env_get_char() into it's only user
  env: Early return from env_get_f() on NULL name
  env: Use strncpy() instead of ad-hoc code to copy variable value
  env: Use string pointer instead of indexes in env_get_f()
  env: Move non-cmd specific env functions to env/common.c
