Clean up redundant ampersand in continuation lines. Line with ampersand at the beginning of the line don't conform to the rest of the model coding standard and are being cleaned up now to improve the coverage analysis. See also CICE-Consortium/CICE#604. The lcov line filtering added there prefers not to have ampersand at the beginning of the line.

Bizarre - not sure why all those are there. Thanks for cleaning up.
