Ugh.
Can you try replacing the grass.mapcalc() call with:
grass.write_command('r.mapcalc', file = '-', stdin = expr)
Or maybe it requires CR+LF on Windows:
expr = "elevation_percentile = (100.0 / 48.0) * \\\r\n(%s)" % " +
\\\r\n".join(terms)
grass.mapcalc(expr)
Alternatively, just omit the line breaks from the expression:
expr = "elevation_percentile = (100.0 / 48.0) * (%s)" % " +
".join(terms)
grass.mapcalc(expr)
I'm not sure whether Windows even allows newlines in command-line
arguments. If it does, then it would suggest a bug in Python's
subprocess module, which handles the conversion of the argument list
to a string.
