You example works only because the continuation starts at position 1.
$ [ -n "${test-name-fowarding}" -o -n "${test-noname}" ] || \
exerr "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
this is for ease of reading the code but will display with a bunch of
spaces in the middle of the sentence. The \ works fine bypassing all
white space between code not so for white space between the " ".
Is there a coding method to get around this?
