; * so-long.el: Documentation and spelling

Reverting certain changes from commits b0f20651e3 and d1a791f8ed.

Please refer to the comments on spelling at the end of the library.
M-x ispell-buffer should find no misspellings in the documentation.
See also test/lisp/so-long-tests/spelling-tests.el

(The current spelling will persist while so-long.el is maintained in
its own Savannah repository, to avoid unnecessary conflicts between
the two versions.  If in the future it is maintained solely in the
Emacs repository, changing the spelling would become an option.)

Note that "mitigations" (plural) is intentional -- this library
identifies a collection of different performance mitigations,
multiple of which will typically be in effect together.
