Please find below a reproduceable situation where help side-effects of
Andy's code appear:
Use vimrc_example.vim completed with Andy's code as .vimrc
Go to home directory
rm .viminfo (DON'T FORGET)
gvim file1
:set insertmode
CTRL-O :h zR
Result: the help window opens at the beginning of fold.txt (not the
correct place)
If :set insertmode is not typed, the problem does not occur.
Do you reproduce that?
Yes. Vim first jumps to the tag, then lastpos jumps to `" which is
initialized with (line 1, col 1).
I added more guards.
Installation (suggestion only):
- disable existing last-position-jump code in the vimrc
- put the attached file in the plugin folder
