tab completion converts input to uppercase

Bug Description

maxima 5.21.1 on Ubuntu 10.10 running under gcl 2.6.7

readline tab completion changes the current input symbol to uppercase. This would be ok if the reader was case-insensitive, which it isn't.

To reproduce: type

sin <TAB>

result: input is changed to "SIN" (which is unknown to maxima).

I'm running the current development version of maxima (which I have compiled myself). ...Seems like the problem is no more present in the upstream source. At least I hope it is.

Weird: The autocompletion code of wxMaxima doesn't contain any command that converts things to uppercase. And it doesn't happen on my computer. Still it happens fore some users => We'll have to find out what is the difference between the computers that work and the computers that don't.

Just for the record: This happens with the commandline version, not with wxMaxima.

That explains why I am not experiencing this even after setting up two test systems (shame on me: There was no indication that this bug is about wxMaxima): I am using wxMaxima. Which is a fine graphical frontend, by the way.

Are you using rmaxima or just a plain maxima?

Plain maxima.

The version I have in front of me right now is 5.37.2-8 - still has the bug.

I've informed the maintainer of the compiler maxima was compiled with. In the meantime I can recommend wxMaxima to you (which has its own autocompletion that isn't affected by this bug) - or to
 - uninstall maxima
 - install the package maxima-common from
 - install the package maxima-sbcl from the same location.

This package should (depending on the problem) be more or less as fast as the maxima you have currently installed and it should not have the autocompletion bug.

Thanks a lot.

So the bug appears only in the gcl version, but not in the sbcl version?
