Description changed by neteler:

Old description:

Add new flag to list inputs and outputs:

{{{
r.mapcalc -l "test1 = test2 + test3 + 5"
input=test2,test3
output=test1
}}}

From #2409:

{{{
Such an option would be fairly simple to add. Most of the relevant logic
is already present in execute() in r.mapcalc/evaluate.c.

The initialize() function populates the list of input maps (in
r.mapcalc/map.c or map3.c), which can be used to generate the list of
inputs. Each top-level assignment expression defines an output.
}}}
