-fix a condition so that fparseln() doesn't report spurious empty lines
eg after 2 comment lines, or on EOF after a single comment line
-no escape character means no escaped characters
modify the previous fix so that no pointless realloc()s are done in
the case of multiple empty continuation lines, and comment the code
to make the logics obvious
fparseln is now part of libc in NetBSD so this changes the previous
revision numbering.
