What were you trying to do?
I'm using csh with the line editing features from "set lineedit",
and M-c (upcase_word) is behaving strangely when used on words
already having uppercase letters in them (such as those on which
<M-c> has been done already). No keybindings have been changed
from the athena defaults.
What's wrong:
Type
echo AbcdEfghIjklMno<C-b><C-b><C-b><C-b><C-b><M-c><M-c>
(where <C-b> is control b and <M-c> is meta c).
The line now appears as
echo ABCDEFGHIJKLMNO
with the cursor on the K.
Cursor motion keys such as <C-a>, <C-b>, <C-f> do nothing
now, and editing keys like backspace, <C-k>, etc., do nothing.
Characters that self-insert will appear if typed, and apparently
are appended to the end of the line (after the "O").
<C-p> and <C-n> do call up the previous or next line in
the history list, but display them starting at whatever
position the cursor is at
echo ABCDEFGHIJ<next line or prev line>
and internally prepend the entirety of the line with the
upcased word to the next or previous line, so the command
that will be executed if you press return is
echo ABCDEFGHIJKLMNO<next line or prev line>
<C-l> will appear to clear the screen and put up a new prompt,
but "echo ABCDEFGHIJKLMNO" will be prepended to whatever you
type.
Now start a new line, and type
echo AbCdEfG<C-b><C-b><C-b><C-b><M-c>
The line is not redisplayed with the word in uppercase, though
it should be. However, pressing return now does in fact
result in it echoing "ABCDEFG" instead of "AbCdEfG".
This odd behavior happens whenever <M-c> is done in the last
word of a line when that last word has already been upcased or
in some circumstances when parts of it are in uppercase.
