As a result of an attempt to save a read-only file from emacs (60C vax),
I have a file in my home directory called "%backup%~". I wanted to look at
it, so I tried typing "cat %^Z" expecting filename completion to work
(it is the only file beginning with "%"). It did not. It ignored the
"%" and instead gave a list of completions containing the entire contents
of my home directory (as if I had typed 'cat " ^Z'). Completing on "%b"
listed all files beginning with b (NOT including the %backup%~ file).
Completing on "%ba" failed.
I did a little testing and observed the following: command completion
assumes that a "%" character on the command line is never part of a
filename. It will complete a filename containing a "%" iff the "%" is
after the substring presented for completion (i.e. a file aaa%a will be
completed normally from the string "aaa" but not from "aaa%").
I know that "%" is sometimes a special character, but filename completion
should never be used when "%" refers to a job. tcsh should be able to treat
"%" as a normal character for lineedit functions.
