Wouldn't it make sense to use this new code (in the CONFIG_ENV_BUFFER_PRINT 
sections) unconditionally instead of the old version? The source would look 
nicer and the resulting image probably smaller.

Some nitpicking comments below.

Please stick with one coding-style rule, either "func ()" or "func()". Since 
this file already uses the "func()" style I suggest to use this version.

Why not fold this "putc()" into the puts() above (replace it with printf)?

Best regards,
