I'm sorry for the problems this caused for you; when I tested the updated xterm terminfo I could not figure out the difference with smm/rmm enabled or disabled, and over time I forgot about the issue. Now after reading #574396 I see that with the xterm resources xterm*metaSendsEscape: false xterm*eightBitInput: false and bash as shell meta-key combinations yield non-ASCII characters, which is not the case when the smm/rmm features are disabled. > Thomas Dickey <dic...@his.com> writes: > >> That's already been discussed in SuSE - it's an issue with bash. >> It should allow the decision whether to enable meta mode to be >> configurable. bash's maintainer hasn't been cooperative. > > As of bash 4.1 (and the corresponding readline 6.1 release), there is now an > enable-meta-key readline variable that has the desired effect.

Regardless of that I think we should disable smm and rmm features for squeeze to avoid breakage on partial upgrades. If bash gets fixed, we can enable them after the release.
