profile parser: firm up and document semantics

Clean up the profile parser, firming up the semantics of exactly what
happens in all cases.  Document it.

There are now no more cases of aborting due to failures caused while
opening, parsing or initialising the profile.  Lines of arbitrary length
are also supported.
