re-search-backward functions docu-string

[Andreas Roehler]

Would consider it helpful, if the functions-docu-string
to `re-search-backward' could give an explicit hint at
the problem with regexp there, i.e. AFAIU repeats as
[somechars]+ have no effect and are the same as
[somechars]. As a result we see constructs

as `skip-chars-backward "somechars"' after
`re-search-backward' in the code.

That's explained in the Elisp-Manual.

However, the remark in the functions-docu-string
"Set point to the beginning of the match"
is easily overseen.

So if it reads there something like

"In contrast to..." I would esteem it much better.

Probably also a hint there onto the Elisp Manual is
appropriate.

Thanks to all.
