In 6.x, the quotes are optional; in 7.0, they're required.
For forward compatibility:
1. The expression should be quoted.
2. There should be a space before the first "=" in the expression.
The reason for the change is that, in 7.0, r.mapcalc uses the GRASS
command-line parser, for consistency with other modules:
r.mapcalc [expression=string] [file=name] [--overwrite] [--verbose]
[--quiet]
The expression= option is the first (i.e. default) option, so the
"expression=" can be omitted, but the expression itself must be a
single argument (i.e. quoted), and must not resemble the "option=..."
form used for non-default options (hence the requirement for a space
before the first "=").
