[R] how to read multiple lines per case

[Michael Friendly]

How can I read a space-delimited file, where the data values for each case
are folded before column 80, and so appear on two lines for each case?

The first few cases look like this

loc type bio H2S sal Eh7 pH buf P K Ca Mg Na Mn Zn Cu NH4
OI DVEG 676 -610 33 -290 5.00 2.34 20.238 1441.67 2150.00 5169.05 35184.5
