Bug#429434: gnome-terminal: accented characters confuse space calculation if LC_ALL=C

[Paolo Benvenuto]

Package: gnome-terminal
Version: 2.18.0-2
Severity: normal

I had to grep in a file looking for an accented vowel, and I could see that after I wrote the 
grep command (without executing it), deleting all the characters confused the terminal.

I wrote:
$ grep molín

then I backspaced it till deleting all the letters. Result: the cursor ended one space more at the left.

I could see that if I write:

$ greo áéíóú
and then I delete with backspace, the cursor goes 5 spaces more to the left than it should.

With normal locale (e.g. in a newly opened terminal) this problem doesn't show.

It seems that the bug appears for the setting of LC_ALL=C

If I set "LC_ALL=", the bug desappears.
