 subword-capitalize at the end of a buffer jumps to the beginning

[Message part 1 (text/plain, inline)]

Hi.

I'm observing subword-capitalize get confused when called near the end
of a buffer. Instead of doing nothing like capitalize-word does,
subword-capitalize jumps to around the beginning of the buffer and
capitalizes something there.

The cause is simple. subword-capitalize does

(re-search-forward "[[:alpha:]]" ....)

and uses the results of this search even if it failed. The attached
patch explicitly checks for search failure and exits the function in
that case.
