tags-query-replace and case-fold-search

[Roland Winkler]

In GNU Emacs 20.4.1 (i686-pc-linux-gnu, X toolkit)
 of Fri Oct 29 1999 on tfkp02
configured using `configure  --prefix=/nfs/common --libexecdir=/nfs/common/lib 
--bindir=/nfs/common/lib/emacs/bin/i686-Linux --with-gcc --with-pop --with-x 
--with-x-toolkit=athena'

Today I was using tags-query-replace in order to do some
replacements on a bunch of files. Some replacements required
case-fold-search set to t, some others required case-fold-search set
to nil. It was rather annoying that tags-query-replace uses the
buffer-local variable case-fold-search in order to determine whether
the replacements are done in a case sensitive way or not. I think
it was much more reasonable if tags-query-replace used, e.g., an
optional argument in order to determine whether the replacement is
case sensitive or not. Or it could use a global variable.

I think that the same applies to the buffer-local variable
case-replace.

Apart from this problem tags-query-replace is an excellent tool!!
