Strange. I do this regularly and have never encountered any issues.

Have you attempted it without any plugins/non-defaults?

$ vim -u NONE file_with_long_lines.txt

Also, is there any difference if you use "gq" to reformat instead of
"gw" (maybe there's something weird in the "maintain the cursor
location" code)?

I presume you mean something like

:g/\%80c/norm gww

For a file that small, that's a ridiculous amount of time, so your
gut reaction is spot on. But I'd far sooner point the finger at some
rogue plugin than point it at something you're "not doing right",
'cuz you *are* doing it right.

The fmt(1) utility might lend a hand here, whether invoked inside vim:

:%!fmt

or externally

$ fmt -80 file_with_long_lines.txt > wrapped_file.txt

There's also a fold(1) utility that behaves similarly, with subtle
nuances in their differences, but for the most part, they should
behave roughly the same for this use-case.

Sorry that doesn't help on Windows by default, but fmt(1)/wrap(1)
should work on any Linux, Mac, or BSD box.
