We can define that backslash is to be also escaped if it is to be used
as variable name:
  weird_var\\\+=abcd

I still think it is far more intuitive than =+.

Anyway, IMO '+' as the last character in varname is a extreme corner
case; I think that no one sane actually uses it.

But even if they did, Simon's patches do not break it. Simon's patches
only disallow it in board environment definition during compilation.

I think it is a completely reasonable thing to diallow board
maintainers (i.e. only U-Boot developers, not users) from using such
construction.

Marek
