[Message part 6 (text/plain, inline)]

An infinite loop occurs when Subword mode is active and
`studlify-word' is run on a word with more than one subword. The bug
seems to have been introduced by changes made to subword.el in commit
6ddc44225e743e2b2a0d5c192f50aefd7a4a915b.

Here is a recipe that triggers the bug, starting from emacs -Q:

 1. Open a new buffer, and type in "subWord".
 2. Activate Subword mode by `M-x subword-mode'.
 3. Move point to the beginning of the line, and run `M-x
    studlify-word'.
