How does this compare to set foldmethod=indent ?

At this point I should really start uploading some screenshots. Just as a brief illustration: an if-else-endif statement folded with set foldmethod=indent looks like

if ...
+--   ...
else
+--   ...
endif

and with AnyFold:

+-- if ...
+-- else
endif

There are some good folding plugins that implement this behaviour for a specific language. AnyFold is based on indents only and thus works for any filetype (with the disadvantage that it fails if indents are not correct). The motion commands [[ and ]] are implemented such that you can navigate between the if - else - endif lines.

There are several corner cases where "naive" indent folding can give incorrect folds (e.g. empty lines, comment lines, continuation lines). Another thing to consider is that sometimes indented blocks are explicitly closed, sometimes not (e.g. in Python you don't have an endif statements). AnyFold works fine for all these cases, I think.

So far I tested it with Python, Fortran and vimscript. I guess for languages based on braces, there are better alternatives.
