The Configuration File
Avoid accidentally creating an empty-looking line
(one that contains only invisible space and tab characters)
file when you really
intend to create a blank line (one that contains only the newline character).
The empty-looking line is joined by
line above it and is likely to cause mysterious problems that are difficult
Prior to V8
the maximum length of any given
line of text was defined
as MAXLINE. That maximum length was
usually 1024 characters, which included the end-of-line character and any
read a line that was longer than MAXLINE, it
truncated that line to MAXLINE-1 and terminated
the result with a zero value. Note that
entire line but ignored the excess characters. This allowed it
to accurately keep track of where the next line started.
has no limit for line lengths.
Prior to V8
the last line in your
file had to end with a newline
character. Some editors, such as
(1), are capable of writing
a file in which the last line does not end with a newline character.
If that trailing newline was missing from the last line,
silently ignored it,
thus treating that line as though it didn't exist.
This has been fixed in V8
