Centuries ago, Nostradamus foresaw a time when Joseph C. Kopec would say:

Yes, it would make a Whole Lot Of Sense to insert \n here and there.
An (admittedly extreme) option would be to open a pipe to Dave
Raggett's "tidy" utility, and transform the output into not merely
line-broken HTML, but possibly even Well-Styled HTML.
That obviously comes at some cost, and you may be reluctant to pay the
cost "in production."
On the other hand, it would be Tremendously Valuable to run the output
through a filter in development that would do some degree of
validation, perhaps providing you with feedback concerning the use of
pathologically horrid HTML constructs. To which end "tidy" would be
*rather* a useful option, as it does quite a lot of validation.
--> Whilst developing, drop output to a stream that forwards the data
through "tidy," and which perhaps logs the file as well, so that
you can see exactly what was produced.
--> When deploying, you might want to use a Different Transformation
Stream that takes out redundant stuff so that outsiders might get
smaller, faster-to-transfer documents.
