In fact, it is not "in the Windows world", but rather "in the badly behaved
editors world". You see, Openoffice, MS Office, and I think even Notepad all
correctly use EOLs where they should be, and Eclipse, ZDE, and I think Scipe
(on all platforms - at least linux) incorrectly leave out the last EOL.
Traditionally, each line in a text file is terminated by the EOL sequence, no
matter the platform, and I think older (perhaps current?) versions of fgets in
C do not recognise a full line until it sees the EOL sequence (I could be wrong
about the specifics - it's years since I did any C programming - but I did read
that people encountered problems when processing 'incorrectly' terminated text
files). There are other problems with leaving out the last EOL in text files.
As well as concatenation, imagine you are processing a stream, line by line.
How do you know whether the last line is valid without an EOL? Maybe the stream
was interrupted or terminated by or for an error, etc. or maybe just that line
If a text file does not end with EOL, how is vim to know whether this really is
a text file or just a binary file that happens to contain a suspicious amount
of ASCII and CR or CRLFs? It is best that vim tell you what is going on, rather
than assume one way or the other, the way the 'file' command does on a single
unterminated line ("ASCII text, with no line terminators").
So you see, vim is doing exactly as it should when it encounters these corrupt
'text' files :)
You encountered this issue when viewing the source of a web page. I believe
this is a non-issue. You are opening up a file in your text editor that was
meant to be parsed by web browsers, which happen to ignore whitespace and other
formatting. Indeed you should not "educate the web masters". They have their
own editors and IDEs. Telling them that you have a problem when opening their
web server's output in your editor will, I believe, only serve to provide a
source of amusement.
