Subject: bug#9954: 24.0.50; query-replace-regexp case-changing functions
Date: Fri, 4 Nov 2011 13:31:07 -0400

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

Starting with emacs -Q, enter the following in a buffer:

ALLCAPS lowercase Titlecase

Move point to the beginning of the first word, and do a
query-replace-regexp with the following target:

  \(\sw+\)

and the following replacement:

  \,(capitalize \1)

Expected result:

Allcaps Lowercase Titlecase

What I get instead:

ALLCAPS Lowercase Titlecase

Calling capitalize-word interactively works as expected.

Using query-replace-regexp with upcase instead of capitalize works as
expected, producing:
ALLCAPS LOWERCASE TITLECASE

Using query-replace-regexp with downcase instead of capitalize is also
broken, producing no visible change:

ALLCAPS lowercase Titlecase
