copy-file has bad default behavior |

This bug report will be sent to the Free Software Foundation,
not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.
In GNU Emacs 20.7.1 (i386-*-nt4.0.1381)
of Tue Jun 13 2000 on buffy
configured using `configure NT'
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
copy-file is inconsistent with other copy tools, such as cp(1). When
invoked from a file buffer, the destination defaults to that buffer's
file, although the prompt (nor the copy-file documentation) do not
indicate this. I.e. consider a scenario where files /a/foo and /b/bar
already exist
C-x C-f /a/foo
M-x copy-file RET /b/bar RET RET
When invoking copy-file, it asks for the source file; specify /b/bar.
copy-file then asks for the desitination; it prompts with the directory
name of the current buffer' file. If you press enter here, then
copy-file will default to copying /b/bar on top of and replacing
/a/foo. You get an option to confirm th
File /a/foo already exists. Copy /b/bar to it anyway? (Yes or No)
but that's a bit late
Note that this is inconsistent with the behavior of
the GNU cp(1) program:
cp /a/foo /b
will copy the file /a/foo into /b/foo
If the current buffer is not a file buffer, the default target appears
to be the default directory, but copy-file "tries" to replace the target
directory instead, and this fails, instead of doing the equivalent of
cp /a/foo /b
I suggest copy-file use the source (file-name-nondirectory ) when the
target is a directory. Further, the prompt for the target should
probably be (concat default-directory "/" (file-name-nondirectory
source-file)) instead of simply a directory name.
If the behavior is not changed, the doc should at least be clearer
and say the default target file is the current buffer's file, if
the buffer has a file.
