bug#21766: 25.0.50; delete-trailing-whitespace sometimes deletes non-whitespace |

Steps to reproduce:
1) wget http://www.metalevel.at/ei/fault1.html
2) emacs -Q fault1.html
3) M-x delete-trailing-whitespace RET
This removes several non-white-space characters, including the whole
line containing "and use it like" (line 83 in the original file),
yielding the following diff against the original file:
http://www.metalevel.at/ei/fault1.patch
Subtle changes in different sections of the file cause different
behaviour of `delete-trailing-whitespace'. For example, if I remove the
initial paragraph (patch: http://www.metalevel.at/ei/fault12.patch) to
obtain the slightly altered file:
http://www.metalevel.at/ei/fault2.html
Then the analogous steps, using fault2.html ($ emacs -Q fault2.html,
M-x delete-trailing-whitespace RET) work as expected, removing only
trailing whitespace characters and leading to the diff:
http://www.metalevel.at/ei/fault2.patch
All steps work as expected in Emacs 24.5, removing only trailing
whitespace characters in all cases.
Thank you for looking into this!
