White space at the end of a line

[Spiros Bousbouras]

I'm thinking of adding a command to vim for removing
white space from the end of each line of a C source
file. Can anyone think of a situation where such white
space might be useful ?

He said "useful", not "obfuscatin g"!

I wouldn't call a construct like

//\<no-space>
printf("Never called!\n");

useful. But thanks for the suggestion.

Consider

#define foo \<space>
#define foo \<no_space>

The behaviours are different.

As others have said, the example presented by vippstar isn't what I'd
call *useful*, except perhaps to determine which programmer to fire.

Before I saw that example, I would have guessed that there's no case
where trailing white space is significant. One exception, sort of, is
that a line-joining \ can't be followed by white space (which is a
dumb rule IMHO), but in that case the white space makes the program
illegal.

However, depending on what text editor you use, it might be convenient
to have blank lines indented by the same amount as the non-blank lines
surrounding them. For example (end-of-line marked with '$'):

int x;$
$
x = 42;$

vs.

int x;$
$
x = 42;$

It makes no difference to the compiler, of course,

This isn't useful either...

puts("Something with a \\<space>
to illustrate a point.");

I can't, but of course a danger with such file modifications
is that (some) source control systems/patchers might be fooled into
thinking you had made many changes, for which others working
on the same code might not thank you.
