Oh, that's interesting, particularly the "for line in readfile()" construct.
I would be scared that readfile() is then carried out every time around the
loop! Or maybe vim is optimised to only read one line at a time this way.
Anyone know? If it just reads the file once at the start of the loop then this
Searchfile() function isn't any more efficient than readfile(). My point was
that it would be nice to have a function that doesn't read the whole file if it
doesn't have to, but then maybe that's what this for-construct does?
Thanks,
Rob.
